This book is about the official MicroPython port for RP2040-based microcontroller boards.
MicroPython is a Python 3 implementation for microcontrollers and small embedded systems. Because MicroPython is highly efficient, and RP2040 is designed with a disproportionate amount of system memory and processing power for its price, MicroPython is a serious tool for embedded systems development, which does not compromise on approachability.
