In the last couple of years, the maker community switched from AVR based micro-controllers (popularized by Arduino) to the ARM Cortex-M architecture. Adafruit was at the forefront of this migration, with boards like the Circuit Playground Express or some of the Feathers.
Adafruit chose to adopt the Atmel (now Microchip) SAMD microcontroller family. Unfortunately for us it is not in the list of platforms with the most Ada support so far (stay tuned, this might change soon ;)).
So I was quite happy to see Adafruit release their first Feather format board including a microcontroller with plenty of Ada support, the STM32F4. I bought a board right away and implemented some support code for it.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
