MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimised to run on microcontrollers and in constrained environments.
The MicroPython pyboard is a compact electronic circuit board that runs MicroPython on the bare metal, giving you a low-level Python operating system that can be used to control all kinds of electronic projects.
MicroPython is packed full of advanced features such as interactive prompt, arbitrary precision integers, closures, list comprehension, generators, exception handling and more. Still, it is compact enough to fit and run within just 256k of code space and 16k of RAM.
MicroPython aims to be as compatible with standard Python as possible to allow you to transfer code with ease from the desktop to a microcontroller or embedded system.
