Wave RP2350A USB Mini Dev Board – 150MHz

The Waveshare RP2350A USB Mini Development Board is a compact yet powerful platform built around the Raspberry Pi–designed RP2350A dual-core microcontroller. Featuring a dual-architecture design (Arm Cortex-M33 and Hazard3 RISC-V cores) running at up to 150 MHz, this board delivers excellent performance for embedded applications. With 520KB of SRAM, 2MB of onboard Flash, and a rich set of peripherals, it’s ideal for rapid prototyping and integration into custom projects.



Its miniature design with castellated edges allows easy soldering to carrier boards, while the onboard USB Type-C connector ensures convenient power and programming. The board also provides 15 multifunction GPIOs, multiple communication interfaces, ADCs, PWM channels, and PIO support for creating custom peripherals. With support for drag-and-drop programming, C/C++, and Arduino IDE, the RP2350A Mini Dev Board is a versatile choice for makers, students, and developers.
