Blinka is our CircuitPython compatibility layer. It was originally written as a compatibility layer to run on top of MicroPython to work on boards such as the PyBoard and allow libraries written for CircuitPython to work. This allowed more library re-use and fewer libraries that needed to be maintained.
Blinka was soon adapted to work on Linux-based Single Board Computers to allow those same libraries to work on boards such as the Linux-based Raspberry Pi computers (not to be confused with the Raspberry Pi Pico microcontrollers). It gained a lot of popularity there was expanded to run on many more boards. It wasn’t used much on MicroPython at that point and there weren’t many guides that showed how to run Blinka over MicroPython.
When we recently tried to run Blinka over MicroPython, there were a few things that needed to be fixed up to get it working. While we were at it, we decided to add support for the Raspberry Pi Pico when running MicroPython…

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.
