GPIO Map
Overview
The Waveshare RP2350B-Plus-W is a compact development board built around the Raspberry Pi RP2350B microcontroller, featuring a unique dual-architecture design that lets developers choose between dual ARM Cortex-M33 cores or dual Hazard3 RISC-V cores at runtime. This flexibility makes it an ideal platform for experimenting with both ARM and RISC-V ecosystems on a single board.
Wireless connectivity is provided by the Raspberry Pi Radio Module 2, which integrates the Infineon CYW43439 chip for WiFi 4 (802.11 b/g/n) and Bluetooth 5.2 support. The board ships with 16MB of onboard NOR flash and 520KB of SRAM, with reserved solder pads for optional PSRAM expansion.
In a Pico-compatible form factor measuring just 51 x 21mm and weighing only 4 grams, the RP2350B-Plus-W exposes 26 GPIO pins with support for 2x UART, 2x SPI, 2x I2C, 3 ADC channels, and 22 PWM channels. Twelve programmable I/O (PIO) state machines enable custom peripheral protocols. Programming is supported via MicroPython, CircuitPython, Arduino (arduino-pico core), C/C++ Pico SDK, and drag-and-drop UF2 flashing over USB.
