The Waveshare RP2350-Zero is a compact development board built around the Raspberry Pi RP2350A microcontroller. It features a dual-core Arm Cortex-M33 processor alongside a dual-core Hazard3 RISC-V processor, clocked at up to 150 MHz, with 520 KB of SRAM and 4 MB of onboard flash memory.

Designed in a Pi Zero form factor with castellated pads, the board can be soldered directly into carrier boards or used standalone with headers. A USB Type-C connector handles programming and power, with support for drag-and-drop UF2 flashing and both C/C++ and MicroPython development environments.
