Some of my favorite small micro-controller platforms (as you might have seen if you have been reading this blog) are Arduino and ESP8266. It seems that there is going ot be some upgrades to those platforms this year.
ESP32
ESP8266 chip is used to build WiFi modules for serial-to-WiFi conversion and Internet of Things applications. ESP8266 turned to be IoT maker’s favorite component for a good reason: Espressif turned the IoT game on its head by releasing a chip with WiFi and a decent embedded processor for under $1 in bulk, and costing not much more than that in a module. A little more than a year ago, the ESP8266 WiFi module showed up uneventfully in Seeed Studio’s store. During the year 2015 the ESP8266 turned to be success because it was “good enough” (it has it’s limitations) and price was cheaper than practically anything else in the market. Now it is widely available in various module formats (NodeMcu dev kit being my favorite for quick hacks) and supported by lots many programming tools.
Now Espressif looking to repeat the success of the ESP8266 with the ESP32, , that should be coming out in 2016. Espressif has been working on the next generation of powerful WiFi-enabled tiny, cheap systems for some time. They have their silicon ready and there are beta test kits already. The ESP32 Beta Units Arrive article tells that are two Tensilica L108 processors running at up to 160MHz, a lot of peripherals including ADCs, DACs, I2C, SPI, I2S, and PWM, more RAM, AES and SSL for security, and Bluetooth Low Energy. WiFi has also been upgraded. It’s already shortlisted as the best new chip of 2016, but other than that, there’s not much more information.
While the features are great, Espressif has said the ESP32 is not a replacement for the ESP8266. They’re different markets, and if you just wanted to add WiFi to a project, there’s no reason not to choose the ESP8266.
ATmega328PB
Most Arduino boards, like for example well known Arduino UNO are based on ATmega328 micro-controller from Atmel (there are nowadays also many Arduinos that use different CPUs). It seem that with ATmega328 you never have enough peripherals for everything you might want to do. Whether it’s hardware-driven PWM channels, ADCs, or serial communication peripherals, we always end up wanting just one more of these but don’t really need so many of those. Bye-bye ATmega328P, Hello 328PB! posting at Hackaday tells that Atmel’s new version of the popular ATmega328 series, the ATmega328PB, seems to have heard our pleas. ATmega328PB combines 32kB ISP Flash memory with read-while-write capabilities, 1kB EEPROM, 2kB SRAM, 27 general purpose I/O lines, 32 general purpose working registers, five flexible timer/counters with compare modes, internal and external interrupts, two USARTs with wake-up on start of transmission, two byte-oriented 2-wire serial interfaces, two SPI serial ports, 8-channel 10-bit A/D converter, programmable watchdog timer with internal oscillator, a unique serial number and six software selectable power saving modes. The device operates between 1.8-5.5 volts. The ATmega328PB supports capacitive sensors: 24 buttons in self-capacitance mode, or up to 144 buttons in mutual-capacitance mode. This ATmega328PB does not native USB thing in it, so if you need USB support, look at the ATmega32U4 as used in Arduino Leonardo board.
So what does this mean for you? It seems that chips are shipping right now, and there’s an inexpensive dev kit available as well. If you write your own code in C,you should be pretty ready to use new feature. With Arduino you might need to wait until new chips find their way to Arduino boards (there does not seem to be DIP version you could plug to Arduino UNO socket) and support for it on Arduino IDE is added (unless you can hack it to it yourself).
Here is ATmega328PB chip pin-out from summary:

Espressif’s ESP RainMaker Brings Simpler Provisioning, Updating, Management to ESP32-S2 Devices
https://www.hackster.io/news/espressif-s-esp-rainmaker-brings-simpler-provisioning-updating-management-to-esp32-s2-devices-3a1e2dd79aef
Espressif, creator of the popular ESP8266 and ESP32 ranges of system-on-chips for the Internet of Things (IoT), has announced the launch of ESP RainMaker — an attempt to simplify and streamline the development and subsequent support of cloud-powered devices.
Designed as the successor to ESP Jumpstart, ESP RainMaker aims to make cloud-powered device development and support as easy as possible.
“This does not require you to write any code in the cloud. The cloud application is built with AWS Serverless Computing at its base, and is designed to achieve optimal scalability and security. The ESP RainMaker phone applications, then, will redraw themselves to present the attributes of the devices to the user. Reading or changing these attributes is as easy as toggling a button on the phone. The availability of Python bindings lets you access the same attributes through a command-line or through Python programs, so that you can then link with any other services. And all of this happens without any configuration of the cloud interfaces, or phone apps. All you should do is continue focusing on the device firmware.”
Designed as a successor to 2019′s ESP Jumpstart platform, ESP RainMaker includes a device agent software development kit capable of handling network provisioning, over-the-air (OTA) updates, and cloud communications; a transparent cloud middleware designed to expose device attributes to phone applications or other third-party services, including voice-activated assistant platforms, powered by Amazon Web Services (AWS); so-called “self-adapting” smartphone applications for Android and iOS devices, allowing for configuration and management of connected devices; and a set of Python bindings for automated communication tasks.

An ESP32 Home Automation Swiss Army Knife
https://hackaday.com/2020/05/14/an-esp32-home-automation-swiss-army-knife/
Thanks to the ESP8266 and the ESP32, we’ve seen an explosion in DIY home automation projects recently. When it only takes $3 and a few lines of code to bring your gadgets onto the network, that’s hardly a surprise. But hacking bare ESP modules onto devices will only get you so far. Eventually you’ll probably want to put together a slightly more mature home automation system, and that’s where things can get a little tricky.
Which is why [Alfredo] created the Maisken Homelay. This device is a one-stop-shop for your home automation needs that leverages the power of the ESP32.
https://upverter.com/design/maisken/19555d1b5c7ce35a/homelay-v101/
The Maisken Homelay V1.0.1 is meant to provide access to a few ESP32 features that may be of interest for home automation projects. The project stems from the features offered by WiFi switches like the SONOFF, but tries to achieve the flexibility often required in DIY home automation projects.

OTA ESP32 GUI Makes Updates Simple
https://hackaday.com/2020/06/23/ota-esp32-gui-makes-updates-simple/
One of the disadvantages of having cheap WiFi-capable boards like those based on the ESP32 is that you have to update them. If you have even a few in every room of your house, it can be a pain to pull them out and connect them to a cable for programming. Over the air programming is a great answer, and [Kevin] shows how you can control the update via a simple GUI.
[Kevin] uses a ready-made OTA library to do the work, but creates a GUI configuration and downloader tool. There is a manual step to force the board into the OTA mode, which might be a mild inconvenience, but it improves security since you need physical access to the device to do an update.
The GUI uses Processing’s Python mode and generates for Windows, Linux, or the Mac. Of course, you can do the same job with a command line interface, which might be more daunting for human operators but would be much easier to integrate with an automated system. For example, you might want to update as part of a Makefile.

A 2mm-thin ESP32-based Bluetooth authenticator with built-in keypad and OLED display
Self-proclaimed “hobbyist hardware enthusiast” Andrey Ovcharov wanted a Bluetooth FIDO2 authenticator, so he did what any self-respecting hacker would do: grabbed an ESP32 dev board and created a prototype. As he continued to iterate on the design, he added an ATECC508A secure element, and eventually a FPC1020AP capacitive fingerprint scanner.
So Ovcharov reimagined the device as credit-card sized PCB! Replacing the fingerprint scanner with a simple capacitive touch keyboard
As we go to press, Ovcharov has implemented the BLE server and FIDO2 endpoints, but it is not yet fully functional. The PCB design is available for interested potential contributors, although anyone can reproduce the project using an ESP32 DevKit and the required parts.

Eschewing Wi-Fi, SparkFun’s Englandsaurus writes a guide on programming an ESP32 to accept over-the-air updates over Bluetooth instead.
SparkFun’s Englandsaurus has published a new guide to over-the-air (OTA) updating an Espressif ESP32 microcontroller, but with a twist: Rather than the more common Wi-Fi connectivity, it uses Bluetooth Low Energy (BLE).
“There are tons of examples out there that show you how to update your ESP32 Over-the-Air (OTA) using Wi-Fi and transferring a binary file through your router, but what if you aren’t near a Wi-Fi router, or simply just don’t want to use WiFi on the ESP32 and still want to update your software wirelessly,” Englandsaurus asks. “This is where this webapp comes in handy.”
“Not only is the app able to flash a binary to your ESP32, but it’s also able to tell if you have the most current software, and also what the most current software is that’s available for your device based on its hardware version. This app takes much of the guesswork away from an end-user who may be utilizing the easy to use, OTA update.”

What if your microcontroller IDE was running on the microcontroller itself and not hosted on the computer you use to do the programming? The greatest legacy of Arduino in all its forms has arguably been a software one, in that it replaced annoying proprietary development environments with one that installed easily on a range of operating systems, was easy to use, and above all, worked. The next level of portability is to get rid of any specialize computer-side software. [Ronny Neufeld] wrote MicroIDE for ESP32 as an IDE accessible through a web browser, which interestingly is hosted on the target device itself.

Just power it on, wait three minutes, and the Peryton will automatically capture all packets likely to contain the network password.
CodemasterPL of maker collective Razor has released a pocket-sized, ESP32-powered standalone sniffer designed to capture EAPOL frames and beacons from nearby wireless networks, capturing the data for later analysis on a laptop or other computer: Peryton.
“Peryton is a tiny Wi-Fi handshakes sniffer. It uses the wireless chip inside the board to listen for Wi-Fi frames and captures handshakes and beacons,”
The Peryton is now available from the Razor Tindie store for $50

The joys of overengineering a simple gift. [Joren] wanted to create a dress for his daughter’s fourth birthday that would react with lights in sequence for a song from Frozen. The dress and an LED strip, along with a digital microphone and a battery were easy to procure. But how to make it all work? An ESP32 did the trick.
While the project’s name–Olaf–sounds like it was from Frozen, according to the GitHub page it actually means Overly Lightweight Acoustic Fingerprinting. Right. However, as the name implies, it can learn to identify any sound you want.
One interesting twist. The code is in C, so running it through Emscripten allows the code to run in your browser and you can watch it work alongside a YouTube video of the movie.
