Waveshare RP2040-One

This is the Waveshare RP2040-One, a development board based on the RP2040/Raspberry Pi Pico with a USB-A plug for connecting directly to your PC for programming!

The board includes 4MB onboard flash memory and comes with the usual great RP2040 features you’d expect from similar boards like the Raspberry Pi Pico, and runs the same programming languages including MicroPython and C/C++.

Waveshare has added a few handy features to this board, including a WS2812 RGB LED (tied to GPIO 16), additional GPIO pins broken out to solder pads, and BOOT/RESET buttons for your convenience.
