Waveshare RP2350A USB Mini Development Board, Based On Raspberry Pi RP2350A Dual-core & Dual-architecture Microcontroller, 150MHz Operating Frequency
The Waveshare RP2350-USB-A Mini Development Board is an ultra-compact microcontroller platform built around the Raspberry Pi RP2350A dual-core (ARM Cortex-M33 / Hazard3 RISC-V @ 150MHz) MCU. Featuring 520KB SRAM, 2MB NOR Flash, a USB Type-C connector, and an integrated USB Type-A port driven via PIO state machines, it provides versatile host and device connectivity. Designed with castellated edges for direct SMD mounting, 15 multi-function GPIOs, drag-and-drop mass-storage flashing, and C/C++/Arduino IDE support, it’s an ideal choice for space-constrained custom electronics and embedded USB peripherals.
