Datasheet

This HAT is our finest to date, full of some really great circuitry. 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 HAT 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

DS1307 Real Time Clock can keep track of time for the Pi even when it is rebooted or powered down, to make

for really nice time displays
