Introduction
RP2040-One is a mini RP2040 development board. The onboard PCB USB-A connector makes it plug-and-play instantly. Mini body, 29 x multi-function GPIO pins (20 x via edge pinout, others via solder points), and the edge of the PCB adopt the castellated design, which can be easily and quickly integrated into your project.
