There are now over 200 boards that support CircuitPython
CircuitPython is one of the easiest way to program microcontrollers. CircuitPython is a programming language designed to simplify experimenting and learning to code on low-cost microcontroller boards.
There are now over 200 boards that support CircuitPython! AND in over 15 languages each for localization. Here they are newest listed first, the Slide Trinkey SAMD21 is board 200! It took about 3-ish years starting with the Circuit Playground Express to get to 100 boards, the 100th board was/is the Open Hardware Summit badge in Jan of 2020 (blog post, and featured on Hackaday). About 1 year later, we are now up to 200 boards, these are boards from the community, companies that are not Adafruit, and entire new businesses / makers using and shipping boards with CircuitPython. Chips supported includes: Espressif, Microchip SAMDs, Nordic, NXP, RP2040s, ST, and more! From Wi-Fi to BTLE, to LoRA, there is an easy and fun way to program micrcontrollers with CircuitPython! There are also over 310 libraries as of April 2021, all to get started fast. And that’s even easier to use now with the new Project Bundle feature for all guides!
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.
