Waveshare RP2350-PiZero

Overview

The Waveshare RP2350-PiZero is a feature-rich development board in the classic Raspberry Pi Zero form factor, powered by the RP2350B dual-architecture microcontroller. It features dual ARM Cortex-M33 or dual Hazard3 RISC-V cores running at up to 150MHz, with 520KB SRAM and 16MB flash, plus reserved PSRAM expansion pads.

What sets the PiZero apart from basic RP2350 dev boards is its rich I/O complement: a mini-HDMI connector providing DVI video output via the RP2350B's HSTX peripheral, a microSD/TF card slot supporting both SPI and SDIO communication, a PIO-USB port for additional USB host/device functionality, and a PH2.0 lithium battery header with onboard charge/discharge management powered by a 2000mA DC-DC regulator.

The 40-pin GPIO header is compatible with Raspberry Pi HATs, exposing 28 multi-function GPIO pins with 2x UART, 2x SPI, 2x I2C, 16 PWM channels, and 12 PIO state machines. This makes it ideal as a compact media player, retro gaming console, data logger, or HAT-compatible prototyping platform. Programming is supported via MicroPython, Arduino, C/C++ Pico SDK, and drag-and-drop UF2 flashing.
