Summary

The RGB-Matrix-P2-64x64 is a full-color LED panel with 64×64 pixels (4096 LEDs) and 2 mm pitch. It is driven via HUB75 headers and can be connected to Raspberry Pi, Pico, ESP32, Arduino Mega 2560 or STM32.

Technical overview

  • Resolution: 64 × 64 = 4096 individual RGB LEDs; 2 mm pitch; panel size approx. 128 × 128 mm.
  • Two HUB75 headers on the board: one for data input, one for output – allows daisy-chaining multiple panels.
  • Control type: synchronous, 1/32 scan driving; viewing angle ≥ 140°.
  • Power: 5 V / up to 3 A via VH4 header; power consumption ≤ 15 W.
  • HUB75 pinout: +5V, GND, R1/R2, G1/G2, B1/B2, row-select A–E, CLK, LAT/STB, OE.
  • Manufacturer-listed compatibility: Raspberry Pi, Raspberry Pi Pico, ESP32 (NodeMCU-32S), Arduino Mega 2560 and STM32F103RB.
  • For Raspberry Pi, connect GPIOs 1–40 per the provided table; up to three panels can be cascaded.
  • Open-source project rpi-rgb-led-matrix provides demos: demo, c-example, minimal-example, text-example, pixel-mover and clock.

Commands and examples – verify before use: 

git clone https://github.com/hzeller/rpi-rgb-led-matrix/
make -C examples-api-use
sudo ./demo -D0 --led-no-hardware-pulse --led-cols=64 --led-rows=64
sudo ./c-example -D0 --led-no-hardware-pulse --led-cols=64 --led-rows=64
sudo ./minimal-example -D0 --led-no-hardware-pulse --led-cols=64 --led-rows=64
sudo ./text-example -f ../fonts/8x13.bdf --led-no-hardware-pulse --led-cols=64 --led-rows=64
sudo ./pixel-mover --led-no-hardware-pulse --led-cols=64 --led-rows=64
sudo ./clock -f ../fonts/7x13.bdf --led-cols=64 --led-rows=64 -d "%A" -d "%H:%M:%S" --led-no-hardware-pulse

Notes and version constraints

  • Pin layout may vary slightly between PCB batches; the physical unit in hand is authoritative.
  • Use only 5 V supply; other voltages can damage the display.
  • Raspberry Pi Pico requires CircuitPython firmware and Mu Editor; without firmware no demo will run.
  • Arduino Mega 2560 is recommended because smaller boards lack memory for large bitmaps.
  • STM32 demo is based on the HAL library; an external 5 V / 4 A supply is required, otherwise possible I/O malfunctions.
  • Text display currently supports font sizes 16×16, 32×32 and 64×64 only.
  • Daisy-chaining multiple panels requires correct mapping of input/output HUB75 headers.
