MicroPython is a lean, efficient implementation of Python 3 designed to run on microcontrollers and other constrained systems, fitting in as little as 256K of code space and 16K of RAM. It includes a compiler, runtime, interactive REPL, a subset of the standard library, and hardware-specific modules for GPIO, SPI, I2C, PWM, Bluetooth, and other peripherals.

Use cases

• program microcontrollers in python
• control gpio pins with python on esp32
• run python on embedded hardware with limited ram
• prototype iot devices with a repl
• blink leds and read sensors using python
• flash firmware onto rp2040 or stm32 boards
• write scripts for constrained embedded systems

When to choose

• you know python and want to program microcontrollers without learning c
• you need an interactive repl on bare-metal hardware
• your device has very limited flash and ram
• you want hardware peripheral access (i2c, spi, pwm) from a high-level language

When to avoid

• you need the full cpython standard library or third-party c-extension ecosystem
• you need maximum performance or hard real-time guarantees
• you are targeting desktop or server applications
• you need large memory footprints or heavy multithreading
