Build large, colourful HUB75 RGB LED matrix displays from a Raspberry Pi without the usual jumper-wire tangle. This Adafruit Bonnet plugs onto the 40-pin GPIO header and drives three parallel matrix strings using the active3 pinout, so it can handle roughly three times as many panels or pixels as the single-panel Matrix Bonnet.
Because this version is focused on driving multiple panels, power for the LED matrices is supplied separately rather than managed on the Bonnet. Adafruit recommends a serious 5V 10A+ supply for the matrices; the Raspberry Pi cannot power the display panels directly. RGB matrices, Raspberry Pi, and power supply are not included.
It works with Raspberry Pi boards that have a 40-pin GPIO header, including Zero, Zero W/WH, Model A+, B+, Pi 2, Pi 3, Pi 4, and Pi 5. Older 26-pin Model A or B boards are not supported. For best performance, a Pi 4 or Pi 5 is recommended; Pi Zero users may need to solder a header onto the Pi first.
For Pi 0, 2, 3, and 4, Adafruit recommends the rpi-rgb-matrix driver with C and Python bindings using the standard/active3 pinout. For Pi 5 and later, use Adafruit’s PIO-based matrix driver, which supports up to 3 panels and includes demo code for the triple bonnet.
Features:
- Simple design: Plug in IDC cables, provide separate power to each panel, and run Adafruit’s Python code.
- Level shifting: Onboard level shifters convert the Raspberry Pi’s 3.3V logic to 5.0V logic for clean, glitch-free matrix driving.
- Fully assembled: Compact design with no soldering required on the Bonnet.
- Raspberry Pi connector: Plugs onto any Raspberry Pi with a 2x20 connector.
- Matrix compatibility: Works with Adafruit 16x32, 32x32, 32x64, or 64x64 RGB LED matrices with HUB75 connections.
- 64x64 support: Select whether the Address E pin is on the 4th or 8th IDC pad using an onboard switch.
- Chainable displays: Chain multiple matrices together for a longer display.
This Bonnet is only for HUB75-type RGB matrices and is not suitable for NeoPixel, DotStar, or other addressable LEDs. A slim 2x20 header is fitted by default; use a 2x20 riser header to lift it above an enclosure, or a 2x20 stacking header if you need GPIO access while it is installed.
Jargon buster
Plain-language definitions for the technical terms used above.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- HUB75
- HUB75 is a common connector and signalling standard used by many RGB LED matrix panels. If a controller supports HUB75, it can plug into compatible matrix panels without custom wiring, but you still need to match the panel size and power requirements.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- NeoPixel
- A type of addressable LED system where colour data is sent along a single digital data line from one LED or controller to the next. Compatibility matters because the timing and signal format must match for the lights or driver board to respond correctly.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
