Micropython Lib
micropython-lib is the official package repository for MicroPython, providing a collection of modules and libraries designed to run on microcontrollers and other constrained devices. It implements a reduced subset of CPython's standard library, adapting familiar Python interfaces to fit within the limited memory and processing power of embedded systems. The project enables developers to reuse existing Python knowledge on MicroPython hardware by offering minimalist implementations of core modules.
The library supports multiple methods for getting code onto devices, including copying single-file modules or directories directly to a device's lib folder, freezing packages into firmware binaries at compile time using manifest files, and installing packages over a network connection with the built-in mip package manager. For host-based workflows, the mpremote command-line tool can transfer packages from a computer to a connected MicroPython board. The repository also accommodates forked package sources, allowing installation from custom GitHub Pages URLs when alternative package indexes are needed.
Beyond the standard library, micropython-lib adapts select third-party Python packages for use in the MicroPython environment, extending the range of functionality available on constrained hardware. The project's packaging model distributes each module as a single .py file or a directory, simplifying manual copying and firmware freezing processes. Documentation covers installation via mip, mpremote, and firmware freezing, providing the essential surface for getting started with MicroPython package management.
