## What it is
PikaPython is an ultra-lightweight Python interpreter written in C that runs on microcontrollers with as little as 4KB of RAM and 64KB of flash, with zero dependencies. It supports Python 3 syntax, works out of the box, and can be easily extended with C modules on platforms like STM32, ESP32, and RT-Thread.

## Use cases
- run python scripts on a microcontroller with 4KB of RAM
- script an stm32 or esp32 device in python
- embed a python interpreter in an iot firmware
- alternative to micropython for low-memory mcus
- extend a python runtime with custom C modules
- prototype embedded hardware logic in python

## When to choose
- your MCU has very limited RAM or flash where MicroPython won't fit
- you want zero-dependency, out-of-the-box Python on embedded hardware
- you need easy C extension integration for native modules

## When to avoid
- you need the full CPython standard library or ecosystem
- you're targeting Linux/desktop/server environments with ample resources
- you need mature community support and extensive library compatibility like MicroPython offers
