The easiest way to program microcontrollers

CircuitPython is a programming language designed to simplify experimenting and learning to code on low-cost microcontroller boards.

When we say easy, we mean it.

With CircuitPython, no desktop downloads are required. Just set up your board and start coding via code.circuitpython.org over USB, WiFi, or Bluetooth.

Create a file, edit your code, save the file, and it runs immediately. There is no compiling needed.

Beginner Friendly

CircuitPython is designed with education in mind. It's an easy way to start learning how to code and you get immediate feedback from the board.

File Storage

The internal storage for CircuitPython makes it great for data-logging, playing audio clips, and otherwise interacting with files.

Easy Code Updates

Since your code lives on the disk drive, you can edit it whenever you like. You can even keep multiple files around for easy experimentation.

Serial Console + REPL

These features allow for live feedback from your code and interactive programming.
