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-1.17.tar.xz (54MiB) 源码可不micro. Python 3.9.0 for Windows 52.1MB. 不过MicroPython像是操作系统和python二合一。MicroPython支持线程。
