Waveshare RP2350-PiZero is an update of the RP2040-PiZero, keeping the Raspberry Pi Zero form factor, but replacing the RP2040 MCU with the more powerful RP2350 dual-core Cortex-M33/RISC-V microcontroller.
The RP2350-PiZero still comes with 16MB flash, a mini HDMI/DVI connector, two USB Type-C ports, a microSD card slot, and a 40-pin GPIO header. It supports 5V power input via USB-C, as well as LiPo batteries via a 2-pin connector and a charging circuit.

- Power Supply
- 5V via USB Type-C port
- 2-pin connector for Lithium battery
- Dimensions – 65 x 30mm
Waveshare provides basic instructions to get started with MicroPython, C/C++, and Arduino in the wiki. You’ll also find a few C or Arduino demos there for DVI video output (PicoDVI fork) via the mini HDMI port, USB host/device using PIO-USB, and the microSD card slot. Those are all projects already available for other Raspberry Pi RP2350 boards, but it’s the first Raspberry Pi Zero lookalike based on this specific MCU we’ve seen.
Waveshare sells the RP2350-PiZero for $17.17 on Amazon and $9.99 on the company’s online store. It’s also sold on AliExpress, just not yet on Waveshare’s store, by third-party stores for an unknown price… (I’m being shown a $0.99 welcome deal most people won’t get…)
