Description The Waveshare RP2350-USB-C is a compact microcontroller development board based on the Raspberry Pi RP2350A. It gives developers a small USB-C board for RP2350 experiments, embedded control, USB host/device testing, MicroPython learning, C/C++ development, and carrier-board prototyping. This product page covers the two official port variants: Waveshare-34641 with PIO-USB female port and Waveshare-34953 with PIO-USB male port. Both variants share the same RP2350A core platform, 520KB SRAM, onboard 2MB Flash, 15 multifunction GPIO pins, and a compact castellated module layout. The key advantage of the RP2350-USB-C development board is its dual-core, dual-architecture design: developers can work with dual Arm Cortex-M33 cores or dual Hazard3 RISC-V processors, with flexible clocking up to 150MHz according to Waveshare. That makes the Waveshare RP2350 board useful for firmware experiments, USB PIO work, classroom demos, and small production prototypes. Features RP2350A microcontroller: Raspberry Pi RP2350A chip for next-generation Pico-style embedded development. Dual-core and dual-architecture: supports dual Arm Cortex-M33 or dual Hazard3 RISC-V processors, up to 150MHz. Memory for real projects: built-in 520KB SRAM with onboard 2MB NOR Flash. USB Type-C workflow: USB 1.1 device and host support, with drag-and-drop programming over USB mass storage. PIO-USB variant choice: choose the PIO-USB female port version or PIO-USB male port version for the target hardware layout. 15 multifunction GPIO pins: useful for sensors, displays, motor-control prototypes, custom buses, and board-to-board wiring. 12 PIO state machines: supports custom peripheral experiments and timing-sensitive protocol work. Development platform support: official page lists C/C++, MicroPython, and Arduino IDE support. Castellated board design: suitable for breadboard-style tests, compact embedded builds, and SMD carrier-board integration.
