The Nabto Platform in a nutshell
Nabto provides a full communication infrastructure to allow real-time direct, secure communication between end-user client devices and IoT devices. The Nabto platform provides direct peer-to-peer connectivity with no firewall or dynamic IP hassle. The platform can communicate any content ranging from simple temperature data to fully fledged audio/video streaming feeds.
The miniUNO is an exact replica of the UNO. Where the main difference between them is the fact that the miniUNO’s size is 1.35″ x 1.05″, while the UNO’s is 2.7″ x 2.1″. And like the UNO, the miniUNO is based on the ATmega328P microcontroller, and is compatible with Arduino IDE and ready to plug and play
There are plenty of USB development boards available that can be utilized for any number of projects, with the most popular being the ATtiny85 and the Teensy line from PJRC.
ESP32-PoE is an IoT WIFI/BLE/Ethernet development board with Power-Over-Ethernet feature. The Si3402-B chip is IEEE 802.3-compliant, including pre-standard (legacy) PoE support. The board takes power from the Ethernet cable and can be expanded with sensors and actuators. Perfect solution for Internet-of-Things projects.
ESP32-POE-ISO has 3000VDC galvanic insulation from Ethernet power.

Australian design house Traverse Technologies has officially unveiled the Ten64, an eight-core ARM64 networking platform designed to ease the development process through the promise of “close-to-mainline” support for Arm’s Trusted Firmware, U-Boot, and the Linux Kernel, ahead of the launch of its crowdfunding campaign — and in doing so has confirmed that its prior Five64 design has been superseded.
Based around NXP’s QorIQ LS1088 system-on-chip, which includes eight Arm Cortex-A53 64-bit processing cores running at 1.6GHz with virtualisation, cryptographic, and input/output memory management unit (IOMMU)
As a network-focused device, there’s no surprise to see an impressive array of connectivity: The board includes eight gigabit Ethernet ports at the rear plus two 10-gigabit Ethernet SFP+ports, all of which can be configured as independent interface
According to a report from the WHO (World Health Organization), approximately 3.8 million people globally are killed by indoor air pollution due to smoke from dirty cooking stoves and fuel. For people living in Third World countries, simply cooking a meal can be deadly, and the mortality rate from that sooty smoke is higher than those afflicted with HIV/AIDS (1.6-million) and malaria (627,000) combined.
“OpenHAP is an open source device used to monitor exposure to pollutants within the indoor household space. It is also very useful for noninvasive monitoring of human habit and actions that may have contributions to pollution, without the need to ask direct questions that may offend or go against culture thus difficult to obtain answers to.”
As the name implies, the OSEP STEM board is an embedded project board primarily aimed at education. You use jumper wires to connect components and a visual block coding language to make it go.
Because the heart of the board is an Arduino UNO clone, you can do anything you like to program it. However, OSEPP touts their visual block diagram language that is basically Scratch. You can use it for free on most platforms and there is even a Web-based version although it can’t download code. It looks like Scratch or other block-oriented systems you’ve seen before.
I’m not usually fond of the visual block languages, but this one at least shows you the actual Arduino code it generates, so that isn’t bad. But you can still use any other method you like such as the standard IDE or PlatformIO.
Cruise around AliExpress for long enough and you’ll find some interesting new hardware. The latest is the TTGO T-Call, an ESP32 breakout board that also has a cellular modem. Yes, it’s only a 2G modem, but that still works in a lot of places, and the whole thing is $15.
On board the TTGO T-Cal is the ESP-WROVER-B, the same module you all know and love that features a dual-core ESP running at 240 MHz with 4 MB of Flash and 8 MB of SRAM. Add to this WiFi and Bluetooth, and you have a capable microcontroller platform. Of note is that this board includes a USB-C port, ostensibly wired so that it behaves like a normal USB micro port. That’s neat, 2019 is the year USB C connectors became cheaper than USB micro connectors.
In addition to the ESP32 module, there’s also cellular in the form of a SIM800 module. This module has been around for a while and used in many, many cellular-connected projects and products like the ZeroPhone.
Engineer Sid Price has officially opened crowdfunding for his latest creation, a debugging probe based on the popular 1BitSquared Black Magic Probe design with a twist: the ability to operate wholly wirelessly via battery power and a Wi-Fi data link.
“And if your target is really remote? Like in another country remote? ctxLink can bridge that gap too. Just configure your router to forward incoming connections for the GDB server port to ctxLink, and your local debugger will gain access to the remote device.”
the ctxLink offers SWD and JTAG debugging interfaces with support for a range of Arm Cortex targets from vendors such as Microchip, Nordic, NXP, and S with target voltages from 1.7 to 5V. In addition to its Wi-Fi connectivity, which can be configured using a smartphone via HTTP Provisioning or using Wi-Fi Protected Setup (WPS), the debugger can be connected via USB for wired use
The USB Armory Mk II is powered by an upgraded 900 MHz ARM Cortex-A7 processor, though it retains the same 512 MB of RAM from the previous version. Like the original, there’s a micro SD slot to hold the Linux operating system, but this time it’s supplemented with an onboard 16 GB eMMC chip. There’s even a physical switch that allows the user to choose which storage device they want to boot from. Other additions for the Mk II include Bluetooth connectivity, and a hardware true random number generator (TRNG).
NXP Semiconductors has announced the i.MX RT1170 “crossover” 28nm fully-depleted silicon-on-insulator (FD-SOI) microcontroller unit (MCU), a power-efficient design which nevertheless manages to clock its primary Arm Cortex-M7 processing core at up to 1GHz while packing a secondary Cortex-M4 core running at 400MHz.
Bulgarian open hardware specialist Olimex has announced a new development board for those looking to experiment with Narrowband Internet of Things (NB-IoT) low-power wide-area network (LPWAN) connectivity: the NB-IoT-DevKit, priced at just €18 (around $20) per board.
Inverse Path, an F-Secure company, has released an open source, flash drive-sized Linux computer designed from the ground up with information security in mind.
Both the USB Armory Mk II and Mk II Debug board have recently launched on Crowd Supply and they have already surpassed their $20,000 funding goal after a few hours.
The small 64.4 × 42 mm (2.54 × 1.65 inch) board is built around an off the shelf ESP-WROOM-32 module. However things get interesting after that, with three independent methods of powering the board; a USB-C connector, a 2.1 mm barrel connector, or via broken-out +V and GND pins, the board can be powered with a 4.5 to 16 V supply.
The on-board USB connector also provides a serial console, and allows you to program the board. The board is has both Wi-Fi, and Bluetooth, provided by the ESP32, as well as an Ethernet jack. The board also has a Micro SD card slot, along with a user addressable LED and button.
The Arduino IoT Cloud has begun supporting a number of third party devices, starting with the uber-popular ESP8266 by Espressif Systems — NodeMCU, SparkFun’s ESP Thing, ESPDuino, and Wemos (to name a few) — along with other inexpensive, commercially available plugs and switches based on this module.

USB-C versus USB Micro connectors are turning into one of the holy wars of our time. Rather than be left on the wrong side of the divide [Stefan S] has come up with his own USB-C version of of an Arduino Pro Micro to avoid having to always find a different cable.
Works on all Arduino IoT Cloud devices — including the newly-supported ESP8266 devices, providing you’re a Create Maker Plan member.
Arduino has announced its first official Alexa Skill, connecting Amazon’s popular voice-activated assistant platform to the Arduino IoT Cloud — and with the promise of no extra coding beyond that required to create the projects in the first place.
“You could use Alexa to turn on the lights in the living room, check the temperature in the bedroom, start the coffee machine, check on your plants, find out if your dog is sleeping in the doghouse… the only limit is your imagination!
“The launch of the Arduino IoT Cloud & Alexa integration brings easy cross platform communication, customisable user interfaces and reduced complexity when it comes to programming,”
Arduino IoT Cloud is primarily designed for microcontrollers featuring a Microchip ATECC508A cryptographic co-processor — meaning the Arduino MKR 1000, MKR WiFi 1010, MKR GSM 1400, and Nano 33 IoT, at present — which handles encryption and authentication; along with adding Alexa support, however, also adds support for ESP8266 devices including the NodeMCU and ESPduino with full SSL encryption — though only for those users with a Create Maker Plan subscription.
Based on the NXP Semiconductors iMX 8M processor, Avnet’s MaaXBoard is ideal for low-cost embedded computing and AI at the edge development: http://bit.ly/2KuqgAT
Arduino C and MicroPython are great for most microcontroller projects, but what if you have only a few kB of flash and RAM to work with? For these cases, you might check out Keith Packard’s “Snek.”
This language — think Snek ~ snake ~ Python — according to his description, “borrows semantics and syntax from Python, but only provides a tiny subset of that large language.
Packard’s been able to get Snek running on two Arduino boards, plus several from Adafruit, and now he’s developed an actual “SnekBoard” capable of controlling LEGO Power Functions motors and switches.
“However perhaps the most interesting thing about the software on the Bangle.js is that there is TensorFlow Lite for Micro-controllers built into the firmware, so you can run machine learning models on your wrist.”
EsmaCAT’s shield feature EtherCAT communication capabilities to connect to the larger Arduino ecosystem.
Austin-based EsmaCAT, a spinoff company from Harmonic Bionics, is set to release their EASE (EtherCAT Arduino Shield by EsmaCAT) shield capable of controlling an entire Arduino ecosystem. EASE offers the same Arduino Uno form factor, and stacks like any other shield. However, this one features the EtherCAT (Ethernet for Control Automation Technology) protocol, which is an industrial Fieldbus designed for automation applications.
EsmaCAT explains, “The base board can read and write a data packet from EASE via SPI, and the same data packet is also read and written by an EtherCAT Master via a standard EtherCAT protocol which is an industrial Fieldbus for high-performance robotics. Multiple EASE boards can be connected with Ethernet cables with a daisy-chain topology, and the power of the system is supplied over Ethernet cables with Power-over-EtherCAT technology.”
The EASE shield bridges the data packets between an EtherCAT-based host board and multiple Arduino (or similar) slave SBCs, which is significantly faster than CAN-bus (200 times faster) and the traditional RS232 serial gateway (1000 times faster).

Works on all Arduino IoT Cloud devices — including the newly-supported ESP8266 devices, providing you’re a Create Maker Plan member.
Arduino has announced its first official Alexa Skill, connecting Amazon’s popular voice-activated assistant platform to the Arduino IoT Cloud — and with the promise of no extra coding beyond that required to create the projects in the first place.
“You could use Alexa to turn on the lights in the living room, check the temperature in the bedroom, start the coffee machine, check on your plants, find out if your dog is sleeping in the doghouse… the only limit is your imagination!
“The launch of the Arduino IoT Cloud & Alexa integration brings easy cross platform communication, customisable user interfaces and reduced complexity when it comes to programming,”
Arduino IoT Cloud is primarily designed for microcontrollers featuring a Microchip ATECC508A cryptographic co-processor — meaning the Arduino MKR 1000, MKR WiFi 1010, MKR GSM 1400, and Nano 33 IoT, at present — which handles encryption and authentication; along with adding Alexa support, however, also adds support for ESP8266 devices including the NodeMCU and ESPduino with full SSL encryption — though only for those users with a Create Maker Plan subscription.

SnekBoard is a Python programmable, open source board for Lego Power Functions motors and switches.
SnekBoard Controls LEGO Motors and More
This open source board is designed to hook up to Lego Power Functions motors and switches.

Arduino C and MicroPython are great for most microcontroller projects, but what if you have only a few kB of flash and RAM to work with? For these cases, you might check out Keith Packard’s “Snek.”
This language — think Snek ~ snake ~ Python — according to his description, “borrows semantics and syntax from Python, but only provides a tiny subset of that large language.
Packard’s been able to get Snek running on two Arduino boards, plus several from Adafruit, and now he’s developed an actual “SnekBoard” capable of controlling LEGO Power Functions motors and switches.

EsmaCAT’s shield feature EtherCAT communication capabilities to connect to the larger Arduino ecosystem.
EASE Is an EtherCAT-Equipped Arduino Shield
https://www.hackster.io/news/ease-is-an-ethercat-equipped-arduino-shield-fd6713d57282
EsmaCAT’s shield feature EtherCAT communication capabilities to connect to the larger Arduino ecosystem.
Austin-based EsmaCAT, a spinoff company from Harmonic Bionics, is set to release their EASE (EtherCAT Arduino Shield by EsmaCAT) shield capable of controlling an entire Arduino ecosystem. EASE offers the same Arduino Uno form factor, and stacks like any other shield. However, this one features the EtherCAT (Ethernet for Control Automation Technology) protocol, which is an industrial Fieldbus designed for automation applications.
EsmaCAT explains, “The base board can read and write a data packet from EASE via SPI, and the same data packet is also read and written by an EtherCAT Master via a standard EtherCAT protocol which is an industrial Fieldbus for high-performance robotics. Multiple EASE boards can be connected with Ethernet cables with a daisy-chain topology, and the power of the system is supplied over Ethernet cables with Power-over-EtherCAT technology.”
The EASE shield bridges the data packets between an EtherCAT-based host board and multiple Arduino (or similar) slave SBCs, which is significantly faster than CAN-bus (200 times faster) and the traditional RS232 serial gateway (1000 times faster).
AB&T Tecnologie Informatiche offers a similar board with the EasyCATArduino Shield, which looks nearly identical to the EASE board but offers a touch TFT display option,
