Waveshare RP2350 One

This small development board is based on the RP2350/Raspberry Pi Pico 2 powered by a dual-core Arm Cortex-M33 and dual-core Hazard 3 RISC-V, running at up to 150 MHz.

It includes 520KB of memory and 4MB of storage, giving you enough space for your code and data. The USB-A connector lets you plug it straight into your computer without needing extra cables, that’s handy!

The board has 29 GPIO pins and communication protocols like SPI, I2C, and UART, making it compatible with a wide range of devices. It also comes with a colourful RGB LED, a user LED, and buttons for booting and resetting. You can even use its programmable I/O tools if you need to connect something like WS2812B LEDs or more I2C/SPI buses than are available.  

In regards to programming, you can drag and drop your code over USB, and it works with coding languages like C/C++ and MicroPython. Helpful guides and resources are included to make getting started easy (See our resources section further down)
