What it is

MicroPython is a lightweight implementation of Python 3 that includes a small subset of the Python standard library. It is designed to run on microcontrollers and in constrained environments, making it ideal for embedded systems development.

MicroPython stands out for its ability to bring the power and simplicity of Python programming to microcontrollers and constrained environments, making it a unique choice for embedded systems development.

When it fits — and when it doesn’t

A good fit for

  • Developers working with microcontrollers who need a Python-like environment for rapid development and testing.

  • Projects requiring minimal resource usage while still benefiting from the flexibility of Python.

Look elsewhere if

  • Applications that require extensive use of Python's full standard library or third-party modules not available in MicroPython.

  • Large-scale applications where performance is critical, as MicroPython may have limitations compared to native code implementations.

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Limited standard library support

    MicroPython includes only a subset of the Python standard library, which can limit functionality for complex applications.

  2. 02

    Performance limitations on microcontrollers

    Due to resource constraints of microcontrollers, MicroPython may exhibit slower performance compared to compiled languages like C or C++.

  3. 03

    Limited third-party library ecosystem

    The availability and maturity of third-party libraries for MicroPython are limited compared to the full Python ecosystem.

What it does well

  • Small footprint suitable for microcontrollers

  • Full Python 3.4+ compatibility with a subset of the standard library

  • Interactive REPL (Read-Eval-Print Loop) for quick prototyping and debugging
