Questions tagged [micropython]

MicroPython is a Python interpreter (with partial native code compilation feature). It provides a subset of Python 3.5 features, implemented for embedded processors and constrained systems.

About

MicroPython is a lean and fast implementation of the Python 3 programming language that is optimised to run on a microcontroller. It was originally created by the Australian programmer and physicist Damien George and first appeared in May of 2014.

The MicroPython board is a small electronic circuit board that runs MicroPython on the bare metal, and gives you a low-level Python operating system that can be used to control all kinds of electronic projects.

MicroPython was successfully funded via a Kickstarter campaign. The software is available to the public under the MIT open source license.
