You can now create a dazzling display with your Raspberry Pi with the Adafruit RGB Matrix Bonnet. These boards plug into your Pi and makes it super easy to control RGB matrices such as those we stock in the shop and create a colorful scrolling display or mini LED wall with ease.
“Bonnet” boards work on any Raspberry Pi with a 40-pin GPIO header — Zero, Zero W/WH, Model A+, B+, Pi 2 and Pi 3. They do not work with older 26-pin boards like the original Model A or B. Note with the Pi Zero you may need to solder a header on the Pi board; it’s normally unpopulated on that model.
This bonnet will make your matrix projects super easy and avoids wiring complexity. Let me break it down for you:
Simple design – plug in power, plug in IDC cable, run our Python code!
Power protection circuitry – you can plug a 5V 4A wall adapter into the bonnet and it will automatically protect against negative, over or under-voltages! Yay for no accidental destruction of your setup.
Onboard level shifters to convert the RasPi’s 3.3V to 5.0V logic for clean and glitch free matrix driving
Fully assembled compact design no soldering required! Plugs onto any Raspberry Pi with a 2×20 connector, and you’re ready to glow.
A 5V power supply is also required, not included, for power the matrix itself, the Pi cannot do it, to calculate the power, multiply the width of all the chained matrices * 0.12 Amps : A 32 pixel wide matrix can end up drawing 32*0.12 = 3.85A so pick up a 5V 4A power supply. We also stock 5V 10A power supplies. Actual power usage will vary with how many LEDs you light up at once.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
