Adafruit RGB Matrix Shield for Arduino

The Adafruit RGB Matrix Shield simplifies connecting HUB75-type RGB LED matrices to Arduino-compatible boards. Instead of wiring up a bundle of individual connections, this shield handles all the routing for you — just solder on the headers and connector, plug it onto your board, and attach your matrix.

Compatible with ATmega328p boards (like the Metro 328), SAMD21 (Metro M0), and SAMD51 (Metro M4). For small displays with low power draw (800 mA or less), you can borrow 5 V directly from the Arduino's regulator. For larger setups, connect a separate 5 V 2 A or 4 A wall adapter directly to the panel.

Key Features

  • Wiring Adapter Shield – Routes all HUB75 data lines from the Arduino header to a standard 2×8 IDC connector
  • Broad Board Compatibility – Works with ATmega328p, SAMD21 (M0), and SAMD51 (M4) Arduino-compatible boards
  • Optional Power Sharing – Borrow 5 V from the Arduino regulator for low-power displays (≤800 mA)
  • HUB75 Matrix Support – Works with 16×32 and 32×32 RGB LED matrices (32-pixel tall maximum)
  • Mini Kit – Some light soldering required to attach headers, IDC connector, and terminal block
Note: The Arduino library only supports matrices up to 32 pixels tall — 64×64 matrices are not supported. ATmega328p boards have limited RAM and may only handle 16×32 or possibly 32×32 matrices. For larger panels, use a SAMD21 or SAMD51 board.

Ideal For

  • Arduino-based LED matrix signage and displays
  • Scrolling text projects
  • Compact LED wall installations
  • Education and prototyping with RGB matrices

Package Contents

  • 1× RGB Matrix Shield PCB (surface-mount parts pre-assembled)
  • 1× 2×8 IDC connector
  • 1× Terminal block
  • 1× Header strips (soldering required)
Tip: For projects with lots of LEDs on at once, use a separate 5 V 2–4 A power supply connected directly to the matrix rather than relying on the Arduino's regulator.
