Adafruit Triple LED Matrix Bonnet for Raspberry Pi - For HUB75

You can now create large, dazzling LED matrix displays with your Raspberry Pi with the Adafruit Triple Matrix Bonnet for Raspberry Pi. This boards plugs into your Raspberry Pi with 2x20 header, and makes it super easy to control three 'strings' HUB75 RGB matrices such as those we stock in the shop and create colorful scrolling displays or mini LED walls with ease. 

Unlike our single-panel Matrix Bonnet, this board can drive 3 panels in parallel, also known as "active3" pinout. This means it can handle approximately 3x as many panels/pixels. However, as a trade-off, the power management is not done on-board. Instead you will have to provide the 5V 10A+ power separately! We recommend two power distribution bus bars, they're good for many amps and make wiring easier.

• "Bonnet" boards work on Raspberry Pi with a 40-pin GPIO header — Zero, Zero W/WH, Model A+, B+, Pi 2, Pi 3, Pi 4, Pi 5 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. For best performance we recommend a Pi 4 or Pi 5.
• For Pi 0, 2, 3, and 4 we recommend the rpi-rgb-matrix driver, with C and Python bindings. It works great, just select the standard/active3 pinout.
• If using a Pi that has PoE headers on it, take care not to press down on the matrix bonnet so hard that it may make contact with the 2x2 PoE pins. A riser header will help keep the board up and out of the way.
• We also have an older, HAT version of our RGB Matrix design. The HAT version does not come fully assembled, does not support 1/32-scan matrices, but does come with a real time clock (RTC)

This bonnet will make your matrix projects super easy and avoid 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 2x20 connector, and you're ready to glow.

Works with any of our 16x32, 32x32 or 32x64 RGB LED Matrices with HUB75 connections. You can also use 64x64 matrices by soldering a small jumper on the PCB. Want more lights? No problem, chain multiple matrices together for a longer display - we've only tested up to 32x128 but it works just fine. The bigger the display the harder it is on the Pi, so keep that in mind if you're using a lower-powered Pi Zero.

Please note: this Bonnet is only for use with HUB75 type RGB matrices. Not for use with NeoPixel, DotStar, or other 'addressable' LEDs.

Each order comes with a fully assembled and ready to go bonnet with all parts assembled. RGB Matrix is not included.

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.

Raspberry Pi not included (but we have 'em in the shop so pick one up, Zero, Model A+, B+, Pi 2 , 3, or Pi 4)
