Datasheet

The matrices use a driver chip that does all the heavy lifting for you: They have a built in clock so they multiplex the

display. They use constant-current drivers for ultra-bright, consistant color (the images above are photographed at the

dimmest setting to avoid overloading our camera!), 1/16 step display dimming, all via a simple I2C interface. The

backpacks come with address-selection jumpers so you can connect up to four mini 8x8's or eight 7-segments (or a

combination, such as four mini 8x8's and four 7-segments, etc) on a single I2C bus.
