MicroPython is a compact implementation of Python 3 for microcontrollers, embedded systems and other constrained platforms, running on many boards and on Unix-like and Windows systems.

What it does

  • Implements most of Python 3.4 syntax, plus async/await and some later features, with a subset of the core datatypes and standard modules.
  • Runs scripts as source (.py) or precompiled bytecode (.mpy), from an on-device filesystem or frozen into the executable.
  • Provides MicroPython-specific modules for hardware such as GPIO, timers, ADC, DAC, PWM, SPI, I2C, CAN, Bluetooth and USB.
  • Supports over twenty ports, including esp32, rp2, stm32, samd, mimxrt, Unix, Windows and webassembly, grouped into support tiers.
  • Most ports need the mpy-cross cross-compiler built first, using make; some ports also use CMake.
  • Microcontroller targets can be as small as 256kiB flash and 16kiB RAM, while 512kiB flash and 128kiB RAM allow a fuller experience.

Beginner
Hardware it needs, as the project states it
Microcontroller targets can be as small as 256kiB flash and 16kiB RAM, although devices with at least 512kiB flash and 128kiB RAM allow a much more full-featured experience. Unix and Windows systems are also supported; building requires bash, gcc and Python 3.3+ as python3.
