Please note: Raspberry Pi and LED matrix not included.”Bonnet” boards work on any Raspberry Pi with a 40-pin GPIO header — Zero, Zero W/WH, Model A+, B+, Pi 2, Pi 3 and Pi 4. 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.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 avoids wiring complexity. Let me break it down for you:Simple design – plug in power, plug in IDC cable, run Adafruits 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 drivingFully assembled compact design no soldering required! Plugs onto any Raspberry Pi with a 2×20 connector, and you’re ready to glow.Works with 16×32, 32×32 or 32×64 RGB LED Matrices with HUB75 connections. You can also use 64×64 matrices by soldering a small jumper on the PCB. Want more lights? No problem, chain multiple matrices together for a longer display – Adafruit have only tested up to 32×128 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 includedA 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*
