There is a large range of STM32 devices, based on an industry-standard core and accompanied by a vast choice of tools and software, makes this family of products the ideal choice, both for small projects and for entire platform decisions. STM32 microcontrollers are supported by a complete range of tools.

The STM32 portfolio features a variety of options, now including Arm Cortex-M cores (M0, M0+, M3, M4, and M7). This gives developers the flexibility to find the perfect STM32 for applications.

Here are some links and information on STM32 based microcontroller boards and how to use them.

Introduction to the STM32 Blue Pill (STM32duino) article at
https://predictabledesigns.com/introduction-stm32-blue-pill-stm32duino/ will tell you how the STM32duino stacks up against an Arduino and how to make it compatible with the Arduino integrated development environment (IDE). Commonly referred to as the STM32 Blue Pill, this board has nearly all the capabilities of the Arduino module but with a cheaper price. There are also issues: It is not compatible with most Arduino shields (due to differences in size and pinouts) and there are some steps that have to be taken before it can run Arduino code

“The iconic board, which first launched back in 2010, has become synonymous with Arduino itself,”

Major sales milestone gives birth to a compact UNO clone, finished in eye-catching black and gold — and even boasting castellated pins.

The first tweak is immediately visible: The iconic Arduino color scheme has shifted to a black-and-gold finish, while the footprint of the board has shrunk to half the size of its predecessor — which does, of course, mean that the Arduino UNO Mini isn’t directly compatible with shields designed for the original UNO, despite mimicking the infamous spacing of its pin headers.

Another tweak is a shift to USB Type-C, in place of full-size USB Type-B. Elsewhere, the specifications are unchanged.

The UNO you know and love, in a brand new mini form factor: 34.2mm x 26.7mm x 8mm worling collectable item.

There are a lot of people that are changing the world by building anything and everything. Arduino is enjoying success in the IoT wave because its easy to use, relatively inexpensive, and supported by a large ecosystem.
Intel’s decision to stop supporting its Arduino products, including Joule, Galileo, Edison and Arduino 101, has left a vacuum in the market.
Arduino’s website, arduino.cc, is visited by 30 million unique visitors per year and boosts about 23 million page views per month.

Arduino is very good for prototyping new ideas. Newer Arduino board with smaller form factors such as the Arduino MKR, Arduino Pro Mini and Arduino Nano, that are appropriate for taking a product to mid-level production levels. For most IoT devices, the performance of the 8-bit AVR and 32-bit Arm microcontrollers that power most Arduino boards is more than sufficient.

Many projects ultimately migrate off Arduino to other solutions — such as ASICs or custom boards — in order to get more performance or a better form factor.
Atmel Studio (now owned by Microchip) allow users to import their Arduino code base into a more powerful development environment.

The board supports multitude of protocols including Bluetooth 5 and Thread. The board can be powered by 5V USB or 3.0-4.2V Li-Ion/LiPo batteries. The board has integrated battery charging, protection and management.

Typical power draw is between 2.0µA in sleep and 5.0 mA peak on maximum TX power. The form-factor is breadboard friendly.

The FrostBite board is programmable by either Nordic Semiconductor’s SDK, or using a new modern C++ -based framework called SnowFlake IoT. The SnowFlake IoT is a new, open-source IoT platform supporting the latest C++17 standards and asynchronous programming. It includes realtime, multithreaded µOS++ IIIe framework.

I have seen the prototypes of the board and development kit, and they loop promising. I know the developers.

The board is available now at Indiegogo campaign at https://www.indiegogo.com/projects/snowflake-iot-frostbite-development-board#/

Available Frostbite Mega kit includes two breadboard-friendly Frostbite boards, an atmospheric sensor card, USB host card and adapter for Arduino shields. Possible applications include for example home automation, weather stations, or indoor air quality and health.

Arduino Create users can now manage and program a wide range of popular Linux SBCs like the UP² board, Raspberry Pi, and BeagleBone.
Today, at Embedded Linux Conference 2018, Arduino announced the expansion of the number of architectures supported by its Arduino Create platform for the development of IoT applications. With this new release, Arduino Create users canmanage and program a wide range of popular Linux® single-board computers like the AAEON® UP² board, Raspberry Pi® and BeagleBone® as if they were regular Arduino boards.

I wrote about this board in Finnish to Uusiteknogia.fi magazine.

This looks interesting. There are a fair number of USB stick computers on the market. the Tomu is different because it id so small it fits entirely inside your computer’s USB port. 

The board is based around Silicon Labs “Happy Gecko” EFM32HG309 Arm Cortex-M0+ microcontroller. It was inspired by the YubiKey 4 Nano. The project is entirely open source with the hardware under the CC BY-SA 4.0 with documentation available on GitHub.
