CircuitPython is open-source software and you can build it yourself! This new guide will give you the basics for setting up your build environment and how to get started building your own firmware images of CircuitPython. You might want to test the latest changes before a release, tweak some settings, turn features on or off, or add frozen modules to your firmware images to save RAM space.
We’ll add more details to this guide over time, but for now, this should get you started. If you have more questions feel free to ask in the #circuitpython channel in discord (https://adafru.it/discord) or in the support forums.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
