Waveshare’s RP2350-Matrix is a Raspberry Pi RP2350A-powered LED matrix board featuring 64 RGB LEDs (8×8 RGB matrix), a built-in 6-axis IMU, and a Dout pin in case the user needs even more LEDs.
The RP2350-Matrix also includes 25 GPIOs along with 12 PIO state machines for custom peripheral support, an on-chip temperature sensor, accurate hardware timers, and support for low-power sleep and dormant modes. It comes with a USB Type-C port for power and programming via USB 1.1 device/host, and an onboard 800mA LDO regulator for stable power delivery. These features make this board suitable for motion sensing and visual feedback.

In terms of software, this board can be programmed with the MicroPython or C/C++ Pico SDK and the Arduino IDE. Waveshare also provides demos (color effects, IMU-controlled games, and temperature-based LED brightness control) in both MicroPython and C/C++, with detailed examples to show the built-in 8×8 RGB LED matrix and QMI8658 6-axis sensor. More information, including detailed features, pinout, dimensions, along setup guide can be found on the wiki.
While it’s the first Raspberry Pi RP2350 board with an RGB LED matrix we’ve seen, we have covered similar development boards such as the C3FH4 RGB / PICO D4 RGB boards, the Waveshare ESP32-S3-Matrix dev board and Vcc Labs’ Nova open-source RP2040 Matrix board. The “RGB” boards feature a 5×5 RGB LED matrix and WiFi and Bluetooth connectivity, while the Nova board features a larger 70-LED matrix but lacks sensors and wireless, and the ESP32-S3-Matrix combines an 8×8 LED matrix with Wi-Fi, Bluetooth, and a 9-axis IMU for a more complete solution.
The RP2350-Matrix board can be purchased for $12.03 on AliExpress and $16.99 on Amazon. You also have the option to buy the board directly from the Waveshare store for $9.99 with bulk discounts, but that price does not include shipping.
