欧姆定律是指在同一电路中，通过某段导体的电流跟这段导体两端的电压成正比，跟这段导体的电阻成反比。该定律是由德国物理学家乔治·西蒙·欧姆1826年4月发表的《金属导电定律的测定》论文提出的。

RP2040 Datasheet

In this book, we’ll look at how to get started with this hardware, and how to work with other electronic components. By the end of the book, you’ll know how to create your own programmable electronic contraptions.

The SDK (Software Development Kit) provides the headers, libraries and build system necessary to write programs for RP2040-based devices such as Raspberry Pi Pico in C, C++ or Arm assembly language.

This book is about the official MicroPython port for RP2040-based microcontroller boards.
