GPIO Map
Overview
The Waveshare RP2350-Matrix is a compact development board that pairs the Raspberry Pi RP2350A dual-architecture microcontroller with an 8x8 WS2812 addressable RGB LED matrix and a QMI8658 6-axis IMU (3-axis accelerometer + 3-axis gyroscope). This combination enables interactive motion-controlled LED displays, simple pixel games, and visual notification systems out of the box.
The board runs on the RP2350A with switchable dual ARM Cortex-M33 or dual Hazard3 RISC-V cores at 150MHz, backed by 520KB SRAM and 16MB flash. The 64-pixel RGB LED matrix draws up to 900mA at full brightness, so a power adapter above 1A is recommended for maximum brightness operation. A DOUT pin allows chaining additional WS2812 LED strips or matrices for extended displays.
With 25 exposed GPIO pins featuring 2x UART, 2x SPI, 2x I2C, 4 ADC channels, 16 PWM channels, HSTX, and 12 PIO state machines, the board retains full prototyping flexibility despite the integrated peripherals. Included demo code provides colorful gradient animations, an IMU-controlled ball game, and temperature-based color control. Programming is supported via MicroPython, Arduino, and C/C++ Pico SDK.
