Pimoroni Interstate 75 W (RP2350) board is designed for HUB75 LED matrix panels

Pimoroni Interstate 75 W (RP2350) is an all-in-one RGB LED matrix driver board designed for HUB75 LED matrix panels commonly used in video walls, advertising displays, and creative signage. Built around a Raspberry Pi RP2350 chip this board also uses the Raspberry Pi’s CYW43439 module for Wi-Fi and Bluetooth and features user buttons, an RGB LED, and a Qw/ST connector for integration with Qwiic/STEMMA QT breakouts.

The kit is compatible with various LED matrix sizes (32×32, 64×64, etc.) and comes in a starter kit with panels, cables, and magnetic feet for quick setup. All these features make this kit useful for applications including real-time data like bus times, air quality, or sensor outputs, dynamic signage, scrolling text, and more.

As this module is built around the RP2350 MCU it can be programmed with CircuitPython, MicroPython, and C/C++ SDK, offering flexibility for developers. You can also use the Arduino-Pico core to program the device with Arduino IDE. The company also provides the most recent version of the MicroPython firmware and example code on GitHub.

Previously we have written about simple LED matrix boards like the Nova LED matrix board with WS2812 addressable LEDs, the Waveshare ESP32-S3-Matrix, and the ESP32-C3FH4 SoC-based C3FH4 RGB / PICO D4 RGB board all of which are basic LED matrix board designed for development or education purposed, but this is the first time we have seen a compact dev board designed to drive industry-standard HUB75 panels.

Pimoroni’s Interstate 75 W (RP2350) HUB75 LED matrix driver board is available at the company’s online store, where you have the option to buy the standalone board which will cost you around $24.10, or you can purchase the complete kit, which includes two 128×64 RGB LED matrix panels, power and data cables, magnetic feet with screw threads, and a USB cable which will cost you $97.40. You can also find a cheap 192 mm x 192 mm HUB75 LED Matrix display on Aliexpress for $14.46 plus shipping only.
