New interesting Arduino platforms

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. The microcontroller on the Arduino board is programmed using the Arduino programming language (based on Wiring and C) and the Arduino development environment (based on Processing). This combination of tools have made it a very easy to use platform for all kinds of experimenters to create many kinds of project hacks and even commercial products. Why the Arduino Won and Why It’s Here to Stay article gives you idea why the platform is so popular. Arduino and it’s tool-set started with 8-bit Atmel microcontrollers, but nowdays the tools can also be used to program also ARM based microcontrollers.

Every now and then different sources show another “Arduino-like platform”. Here are pointers to some most interesting looking new Arduino platforms (look interesting but I have not had change to personally test any of them):

EDN magazine article Coin-sized Arduino-compatible computer with Bluetooth LE wirelessly connects to smartphones, tablets tells that about the world’s first ‘Arduino’ compatible open-source micro-computer that can communicate wirelessly with any Bluetooth® v4.0 compatible smartphone or tablet. This ‘RFduino’ is based on nRF51822′s powerful on-board 32-bit ARM Cortex M0-based processor. Open Source RF claims that the overriding focus of the RFduino is on building new wireless applications. The RFduino can be powered by anything from household outlets down to a regular CR2032 coin cell (watch) battery. The RFduino 7 GPIO lines all support, Digital IO, Analog ADC, SPI, I2C, UART and PWM. The RFduino is similar to the Arduino UNO or DUE, except the RFduino is a fraction of the cost and size, in addition has wireless smartphone connectivity built-in! There are several open-source RFduino and iPhone apps which are free to use, extend, and share.

The JeeNode is a small wireless board with an 8-bit Atmel RISC microprocessor. JeeNodes are compatible with the Arduino platform and can be programmed under Windows, Mac OS X, or Linux using sketches created with the Arduino IDE. Kits include the ISM-band 868 MHz radio module as used in Europe for short range wireless communications.

The PICnDuino Review page tells about PICnDuino board. The PICnDuino is an Open Source dual microcontroller development platform built into a tiny direct to USB device. It is compatible with both Arduino (Atmega 328P) and Amicus18 (PIC18F25K20). The PICnDuino provides a fantastic opportunity to learn two programming languages in one device (Arduino which is C and Amicus18 which is Basic). You just plug it in to USB and start coding. The board has LEDss onboard and had bread-board friendly format.

CuteUino: Only use the parts of the Arduino that you need for each project article tells of a new small version of the Arduino that has a fitting within the outline of an SD card. In this design the Arduino platform is broken it up into several modules (that you can stack on top of each other) so you can choose only the components that you need for the project. For more details check Prototyping The CuteUino web page.

    Arduino-Compatible Spartan-6 FPGA Board

    An FPGA development board in an Arduino compatible form factor. Hackaday developed awesomeness.

    Product Info

    Shield-form-factor for programming from Arduino or other SPI device
    Standalone JTAG programming for more seasoned designers
    Power rail regulates 3v3 from Arduino 5v or from external supply
    Black solder mask makes you feel awesome

    Don’t call it an Arduino Shield. This FPGA awesome-ness can function autonomously from an Arduino. So why is it in the shield form-factor?

    If you just want to dabble, connect it to your Arduino and use that to program the SPI flash that loads the FPGA. But as you get hooked on FPGA programming — and you will — you’re going to want more. At that point it’ll be easy to justify the subsequent purchase of a proper JTAG programmer.

    As for the chip in question, a Spartan-6 is the real deal. This is what you want to start off with because there’s a lot of room for your own growth. Matt did an excellent job of designing the power rails so that you can hang ever more complex hardware off of the pins (exceeding the current draw limits that come with sourcing from an Arduino’s USB rail).

    But hacking on FPGA is good brain work for those who have only tried out embedded thus far. Coding for hardware is pretty easy to get into — there’s a ton of examples out there already.

    This Arduino-Compatible FPGA Shield was developed by Matt Berggren. He has documented the entire Open Hardware adventure on his project page.

    Phoenard, A Prototyping Gadget

    Phoenard is a Kickstarter project the guys launched at the prize party, something they could attend as a little side trip after manning the ‘maker’ part of the Atmel booth at Electronica. They’ve come up with a tiny handheld device that can only be described as a ‘gadget’. It has a touchscreen, a battery, an MegaAVR, a few connectors, and not much else. What makes this project cool is how they’re running their applications. A bootloader sits on the AVR, but all the applications – everything from a GSM phone to an MP3 player – lives on a microSD card.

    The Phoenard guys have come up with a few expansion modules for Bluetooth LE, GSM, GPS, and all the usual cool modules.

    Phoenard : The Arduino-compatible Prototyping Gadget

    Phoenard is an All-in-one Arduino-compatible prototyping Gadget powered by an 8-bit AVR ATMEGA2560, identical to the one you find in Arduino Mega. It is essentially a pocket-sized prototyping platform which you can use as the ‘brain’ in your projects, similar to using an Arduino. BUT, it has a lot more features built into a single case developed in such a way that you can use it as your day-to-day Gadget.

    TinyScreen Lets You Put A Tiny Screen On It

    Need to put a tiny screen on your tiny thing? Is it your life’s mission to play Flappy Bird on the smallest device possible? Do you have excellent vision? Then put a TinyScreen on it!

    This surprisingly clever little screen is about as big as a postage stamp and it works with the Tinyduino programmable board. The screen is small enough to fit into a watch casing and you can even use it to play games and get tiny notifications.

    The Akron, Ohio-based team has worked with tiny stuff before. Their own Tinyduino boards are built specifically to work with the TinyScreen. The screen costs $25 for just the display and $55 for the display, controller boards, and battery. You can even buy little kits that make gaming consoles, video players, and watches.

    TinyScreen: A color display the size of your thumb!

    TinyScreen is a tiny customizable display. Play games, get notifications from your phone and display useful information.

    TinyScreen is the new way to visualize your environment. With a beautiful color OLED display, TinyScreen is designed to be used to display information from the TinyDuino platform, which stack together like little electronic Lego’s.

    With TinyScreen there are several default apps that will work right out of the box – like a Smart Watch app, a Video player app and a video game app. You can use these default apps with NO PROGRAMMING AT ALL!

    Create your own smart watch using TinyScreen. The watch can be configured to use several different watch faces, and can use Bluetooth 4 (also known as Bluetooth Low Energy and Bluetooth Smart) to communicate with your smart phone (Android 4.3+ and iOS 7+).

    We have an open source app developed for both iPhone and Android that will allow you to configure the notifications that you can receive and display on the watch, like incoming phone calls, incoming texts, tweets and appointments.

    Play games on your TinyScreen, either with the four buttons along the side of the screen, or with the new Joystick TinyShield.

    We’ve written an Arduino library from scratch for the TinyScreen that is optimized for speed and performance, yet still is very easy to use.

    Arduino LED controller shield makes complex RGB LED lighting apps a snap

    Infineon’s RGB LED Lighting Shield is one two of Arduino-based evaluation boards created to showcase the capabilities of its ARM-based XMC1000 MCUs in lighting and motor control applications. Unlike previous semi makers, such as Microchip and STMicro who initially focused on producing Arduino MCU boards which used their own MCUs as alternatives to the Atmel AVR, Infineon has chosen to create plug-in shields which make it easier for developers to more fully explore the processors’ capabilities. Both shields are designed to plug directly into any Arduino Uno R3 board. It is also directly compatible with the Boot Kit for Infineon’s XMC1000 series 32-bit microcontroller family, which is based on the ARM Cortex-M0 processor.

    The Arduino-compatible lighting RGB LED lighting shield reviewed here was designed to give designers a low-cost easy-to-use open-source platform for fast prototyping and inexpensive evaluation of multiple LED light engines. It is based on a XMC1202 MCU which integrates an ARM Cortex-M0 processor and a dedicated Brightness & Color Control Unit (BCCU) core. The BCCU contains 3 independent dimming engines with 9 independent Pulse Density Modulated (PDM) channels. Due to space limitations on the PCB, the shield only provides access to 1 dimming engine and 6 channels. The shield includes an I2C bus which the MCU uses to communicate with a host controller. The shield’s reference firmware supports 10 basic sets of commands which can be used alone or in combination to produce a wide range of lighting effects.

    Infineon says that the BCCU automated hardware engine provides a cost-effective, flexible tool for creating flexible high-quality LED lighting applications. The Shield is designed to be easily modified and expanded as required by a particular application. For example, the MCU’s I/O can be configured to support a DMX lighting control bus and the shield’s scratchpad area makes it easy to add additional hardware, such as a 24GHz radar sensor, commonly used for motion detection

    The Qduino Mini embedded processor board which made its debut on Kickstarter earlier this week will make it easier than ever for Arduino enthusiasts to design and build compact, battery-powered projects. Despite its compact 1in x 1.5in form factor, the board packs all the punch of its full-sized counterparts and throws in a turnkey battery fuel gauge and charger just for grins.

    Quin says he came up with the idea of the ¼ size full-function board while he was working on some of his own projects whose form factors had limited space for electronics and made it tough to change batteries (you can see a couple of those projects in the photo above). As a result, his Arduino Leonardo-compatible board sports an 8MHz ATmega32U4 Processor (32KB Flash, 2.5KB SRAM, 1KB EEPROM), a LiPo Battery Charger and fuel gauge (MCP73832/MAX17048), and a connector for an external LiPo cell (not included due to shipping restrictions). Now you can charge your Arduino-powered project in 1 – 2 hours (depending on battery size) on any standard micro-USB port.

    If you’re having second thoughts about buying a computer board designed by a 14-year old, you need to know that Quin hasmore successful electronic products on the market than most entrepreneurs two or three times his age.

    Quin’s venture since the early days when he developed a few accessories to make tinkering with Arduino systems faster and easier.

    Arduino Zero Pro Soft Release?

    There’s an updated product page for the Arduino Zero, now called the Arduino Zero Pro, up on, one of the two dueling “Arduinos”.

    We first covered the Arduino Zero in May 2014, and shortly thereafter even got to see a development prototype in the flesh. Based an Atmel’s ARM Cortex-M0+ chip, it’s built on a faster processor than the AVR Arduini, and it includes Atmel’s Embedded Debugger which serves as a USB-to-serial channel and on-chip debugging peripheral. But so far all we’ve seen is the prototype.

    Arduino Zero Pro

    The Arduino Zero Pro represents a simple, yet powerful, 32-bit extension of the Arduino UNO platform. The board is powered by Atmel’s SAMD21 MCU, featuring a 32-bit ARM Cortex® M0 core.
    With the addition of the Zero board, the Arduino family becomes larger with a new member providing increased performance.
    The power of its Atmel’s core gives this board an upgraded flexibility and boosts the scope of projects one can think of and make; moreover, it makes the Zero Pro the ideal educational tool for learning about 32-bit application development.
    Atmel’s Embedded Debugger (EDBG), integrated in the board, provides a full debug interface with no need for additional hardware, making debugging much easier. EDBG additionally supports a virtual COM port for device programming and traditional Arduino boot loader functionality uses.

    Hackaday Prize Entry: An SD Card Arduino

    About a year ago, Intel announced they’d be launching a new platform stuffed into an SD card. Imagine – an entire computer packaged into an SD card, with nine whole pins for power and I/O. Cooler heads prevailed, the Intel Edison was launched, but the idea stuck; why can’t you fit an Arduino in an SD card?

    [kodera2t] found out there’s no real reason why you can’t put a small microcontroller inside an SD card. For his Hackaday Prize entry, he created the SDuino, and it’s exactly what it says on the tin: an ATMega328p stuffed into a microSD adapter.

    SD card sized board, let’s say “SDuino”!

    As shown in above image, I assigned several non-standard function to SD card interface, but I needed to be careful for VCC and GND, not to make short circuit even if my wife puts it to computer by mistake. A0 is assigned to one of GND, which will not make fatal side-effect for computer connection.

    Speech Recognizer / Synthesizer Shield for Arduino & Other MCUs

    A Kickstarter project the just launched promises a rather interesting speech recognizer and synthesizer shield for use in hobby projects and embedded systems.

    For the last couple of years, I’ve been waffling on about how embedded vision and embedded speech capabilities are racing towards us.

    We are still in the early days with regard to the widespread use of this technology, but it’s coming — oh yes, it’s coming.

    In the case of speech recognition, one option is to perform all of the processing wirelessly, online, in the cloud. This is the way the Amazon Echo works

    An alternative cloud-based scheme is to have your speech uploaded and evaluated in the cloud, which then returns an ASCII-based text equivalent of what you said. It’s then your job — or the job of your software application — to parse this ASCII text and decide what to do with it.

    Another approach is to perform the speech recognition locally, offline. Now, as you may recall, I have a lot of Arduino-based hobby projects on the go.

    There are a number of speech-recognition shields available for the Arduino. A friend of mine recently purchased one for around $50, but he said it was pretty unintuitive and not-so-easy to use. Also he had to train it to his voice — he later decided to splash out an additional $200 to get the package that made it speaker-independent.

    All of which leads us to this Kickstarter project that just launched earlier today. This is for a standalone (offline) Arduino speech recognizer/synthesizer shield called MOVI

    This little beauty will be able to recognize hundreds of sentences of the user’s choice, where these can range from simple and generic (“Light on”) to complex and specific (“Turn on the ceiling light in the bedroom”).

    From what I’ve seen on the Kickstarter videos, MOVI really does look rather interesting.

Although intended primarily for “mainstream” embedded developers, the board and associated development tools make it easy and affordable for the Maker/DIY-er crowd to get their hands on the STM32F7*, STM’s the latest and highest-performing Cortex-M7 core. Developers involved with Connected Lighting and other Smart Home/Smart Building applications will also find this a great way to see if STM’s most IoT-capable MCU is a candidate for their next project.

    Priced at $49.90, the Discovery Kit’s open hardware architecture provides an affordable, compact platform which includes a WQVGA touchscreen color display, stereo audio, multi-sensor support, security, and high-speed connectivity. Unlimited expansion capability is provided through the Arduino Uno connectivity support and immediate access to a large choice of specialized add-on boards.

    The STM32F7 Discovery Kit comes with ST’s STM32Cube firmware library, as well as direct support from a wide ecosystem of software-development tool partners and the ARM® mbed™ online community.

    SD card sized board, let’s say “SDuino”!

    Once I was excited to see Intel’s announce that they will release “SD card sized computer” but it was not true. This time I made it true!

    Once I was excited to see Intel’s announce that they will release “SD card sized (SD card shaped) computer”, but it was not true. This time I made a real SD card sized full programmable (indeed, Arduino pro compatible) small computer board!

    It consists of ATMega328P and four LEDs connected to D6 to D9. (red, blue, green, white).

    I assigned several non-standard function to SD card interface, but I needed to be careful for VCC and GND, not to make short circuit even if my wife puts it to computer by mistake.

    All the SD card are required to have mandatory lower compatibility to SPI mode. The key is, SD card interface equipped components are not responsible for that. But I naively thought some computer might talk SPI command through SD card interface… I quickly checked it!

    By the way, SDuino case, you don’t need “SDuino writer” just to run your program. Just inserting is enough

    Just pre-programming and pass it to your friend and you can ask it to work just inserting to SD card connector!

    Arduino (PCI) Express

    If you ever wanted to prototype something on PCI Express, you’d usually turn to an FPGA. However, [moonpunchorg] posted a workable design for an Arduino on a mini PCI Express board. (As [imroy264] points out in the comments, the board is using the USB port present on the PCI-E connector.) The design files use KiCAD so it should be fairly easy to replicate or change. Naturally, there are pins on the edges to access I/O ports and power. You do need to use ISP to program the Arduino bootloader on the chip.

    The board appears to a host computer as a SparkFun as a Pro Micro 3.3V board, and from there you could easily add function to a computer with a PCI Express slot using nothing more than the Arduino IDE.

    MicroZed prototyping platform teams with Arduino

    Prototypes developed with the Avnet MicroZed carrier card kit combine the MicroZed system-on-module (SOM) with the large ecosystem of Arduino shields for use in such applications as industrial control, remote sensing, embedded vision, and many other IoT systems. The carrier card provides an Arduino Uno R3-compatible shield interface that connects to the programmable logic I/O on the MicroZed SOM, allowing designers to custom-tailor interfaces between the shield circuits and the programmable logic.

    In addition, the carrier card includes a subset of Arduino-compatible connectors for interfacing the MicroZed SOM to a low-power MCU evaluation board. The interface not only provides connectivity between the MCU and the processing system in MicroZed’s Zilinx Zynq-7000 all-programmable SoC, but also allows the MCU to control MicroZed’s power rails. This enables use cases where power consumption can be reduced by offloading routine tasks to the MCU, while reserving Zynq SoC operation for the functions that require its unique processing capabilities.

    The Avnet-designed MicroZed carrier card kit for Arduino costs $89. The MicroZed SOM is sold separately.

    A single layer all through hole PCB layout for a simple Arduino clone with USB!

    The Frienduino is an Arduino clone you can make for a friend once you have any kind of Arduino and some soldering skill. The board is easy to make (single sided) and easy to solder (only through hole components). It has everything to get started yet it is cheap and simple because it saves on stuff the novice doesn’t need

    IMHO, what made the Arduino so popular is its USB connectivity. This lowers the entry barrier to near zero. No messing around with programmers, no legacy serial port required.

    Rainbowduino v3.0

    The Rainbowduino board is an Arduino compatible controller board with professional multiplexed LED driver. It can drive an 8×8 RGB Led Matrix or a 4x4x4 RGB LED Cube in common Anode mode. Rainbowduino v3.0 uses two MY9221 chips which is a 12-channels (R/G/B x 4) constant current Adaptive Pulse Density Modulation(APDM). Rainbowduino v3.0 has provisions for cascading more such boards with I2C interface.

    Rainbowduino v3.0 is flashed with Arduino boot-loader and this makes it easy to program sketches using Arduino IDE. Unlike other LED drivers, this comes with a USB to UART (FT232RL) inbuilt for programming the sketches.

    Stuffing Everything on a DIP32 Package

    Putting an full microcontroller platform in a DIP format is nothing new – the Teensy does it, the Arduino nano does it, and a dozen other boards do it. [Alex] and [Alexey] aren’t content with just a simple microcontroller breakout board so they’re adding a radio, an OLED, an SD card reader, and even more RAM to the basic Arduino platform, all in a small, easy to use package.

    The DIPDuino, as [Alex] and [Alexy] are calling it features an ATmega1284 processor. To this, they’re adding a 128×32 pixel OLED, a micro SD slot, and 1Mbit of SRAM. The microcontroller is a variant that includes a 2.4 GHz Zigbee radio that allows for wireless connections to other DIPDuinos.

    Arduino’s Long-Awaited Improved WiFi Shield

    Announced at the 2014 Maker Faire in New York, the latest Arduino WiFi shield is finally available. This shield replaces the old Arduino WiFi shield, while providing a few neat features that will come in very handy for the yet-to-be-developed Internet of Things.

    While the WiFi Shield 101 was announced a year ago, the feature set was interesting. The new WiFi shield supports 802.11n, and thanks to a few of Atmel’s crypto chip offerings, this shield is the first official Arduino offering to support SSL.

    The new Arduino WiFi Shield 101 features an Atmel ATWINC1500 module for 802.11 b/g/n WiFi connectivity. This module, like a dozen or so other WiFi modules, handles the heavy lifting of the WiFi protocol, including TCP and UDP protocols, leaving the rest of the Arduino free to do the actual work.

    Also included on the WiFi shield is an ATECC508A CryptoAuthentication chip.

    This is perhaps the most interesting improvement over the old Arduino WiFi shield, and allows for greater security for the upcoming Internet of Things. WiFi modules already in the space have their own support for SSL, including TI’s CC3200 series of modules, Particle‘s Internet of Things modules, and some support for the ESP8266.

    Arduino WiFi Shield 101 is now available in the US store!

    ‘Arduino on Steroids’: FPGA-based XLR8 at ESC Minneapolis

    Even with the same clock frequency as a regular Arduino, the FPGA-based XLR8 can accelerate things like floating-point math and perform other tasks much better.

    Alorium Technology will also be at ESC Minneapolis. And the reason that’s of interest is that these little scamps have created an FPGA-based board called the XL8R (“Accelerate” — get it?) that has the same footprint and behaves just like an Arduino Uno on steroids.

    The regular Arduino Uno has a 16 MHz clock and does things in a certain way. The last thing a user wants to do is swap this out with something that runs much faster, for example, but that doesn’t work with any of that user’s existing shields. Thus, the XLR8′s FPGA has been configured to look exactly like the microcontroller (MCU) powering the Arduino Uno, down to the fact that it also employs a 16 MHz clock.

    At this point you may be saying to yourself “But if it walks exactly like an Arduino Uno, and if it talks exactly like an Arduino Uno, then why don’t I just use an Arduino Uno and have done with it?” Ah, but there’s more… there’s so much more…

    Let’s start with floating-point math, for example.

    By comparison, the XLR8 has dedicated floating-point hardware programmed directly into the FPGA’s fabric.

    And there’s more. One of the things a lot of Arduino users want to do is create robots and control servos. One of the problems is that servicing interrupts can result in “twitching” on the servos. By comparison, the XLR8 has dedicated servo functions

    Well, I just got off the phone with Jason Pecor from Alorium Technology. Jason tells me that they are planning on tackling a variety of issues people have with the regular Arduino. And for each of these solutions, the user’s programs will remain unchanged apart from swapping out an existing library call with its XLR8 counterpart. For example, since so many people are using WS2812-based LEDs — like Adafruit’s NeoPixels — this is a target that’s firmly in Alorium’s sights, which explains why I’m currently performing my happy dance (avert your eyes; it’s not a sight for the young or faint-of-heart).

    Accelerate Your Project with XLR8!

    Arduino 32-bit board offers WiFi connectivity

    With built-in WiFi capability, the MKR1000 development board from Arduino provides a simple way to add wireless connectivity to IoT battery-powered projects. The Arduino MKR1000, also known as the Genuino MKR1000 outside the U.S., combines the functionality of the Arduino Zero and the Arduino WiFi Shield in a tiny form factor.

    The new board is powered by an Atmel ATSAMW25 SmartConnect module, which comprises a SAMD21 32-bit ARM Cortex-M0+ MCU, an ATWINC1500 2.4-GHz IEEE 802.11 b/g/n WiFi system-on-chip, and an ATECC508 CryptoAuthentication IC. It also furnishes a single 1×1 stream PCB antenna.

    The Arduino MKR1000 runs on a 3.7-V, 700-mAh (minimum) lithium polymer battery or an external 5-V power supply. An onboard charging circuit will charge the LiPo battery while the board is running on external power, switching from one source to the other automatically.

    The MKR1000 will be available for purchase in February 2016.
