A lean and efficient implementation of Python 3 for microcontrollers, embedded systems, and constrained platforms.
MicroPython is a lean and efficient implementation of Python 3 designed specifically for microcontrollers and constrained systems. It brings the Python programming language to embedded devices, allowing developers to write hardware-interaction code with Python's simplicity and readability. It solves the problem of programming low-level hardware with complex C/C++ code by providing a high-level, accessible scripting environment.
Embedded systems engineers, IoT developers, hardware hobbyists, and educators who want to program microcontrollers and constrained devices using Python instead of lower-level languages like C or assembly.
Developers choose MicroPython because it dramatically reduces the complexity of embedded programming while maintaining compatibility with Python 3. Its unique selling point is bringing a full-featured, high-level language to resource-constrained devices where traditional Python implementations cannot run.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Supports over twenty ports including Tier 1 actively maintained platforms like ESP32 and STM32, enabling Python on diverse microcontrollers.
Implements Python 3.4 syntax with async/await, allowing developers to use familiar high-level language constructs for embedded coding.
Provides MicroPython-specific modules for GPIO, SPI, I2C, etc., enabling direct hardware access without writing C drivers, as noted in the README.
Runs scripts from source or precompiled bytecode (.mpy), and supports on-device filesystems or frozen firmware, offering deployment versatility.
Only a subset of Python modules is implemented, with poor compatibility for many CPython libraries, limiting code reuse and functionality.
Ports are split into support tiers, leading to inconsistent feature availability and maintenance levels across different hardware platforms.
Requires building mpy-cross and managing submodules for many ports, adding steps compared to precompiled firmware distributions.
