Development board introduction

The Banana Pi Pico series is a low-power microcontroller development board designed for the Internet of Things.

BPI-Pico-RP2040 is a microcontroller development board launched by Banana Pi equipped with RP2040 chip. Its most notable feature is to add a Onboard WS2812 color LED; replace the 3-Pin DEBUG interface with a SH 1mm 4-Pin socket, which can be connected with Qwiic & STEMMA QT or any possible peripherals; replace the micro-USB socket with a USB Type-C socket , supports reversible insertion, and is compatible with the USB Type-C cable of most modern smartphones, no additional purchase is required.
