CircuitPython is a beginner-friendly version of Python designed for microcontrollers. It allows you to write code directly on the device, making it easy to test and iterate on your projects.

CircuitPython is a programming language designed to simplify experimenting and learning to code on low-cost microcontroller boards. With CircuitPython, there are no upfront desktop downloads needed.

Developing in CircuitPython is easy because the entire environment — the code, toolchain, and the devices — are all extremely portable.
