This is a mini 8×8 matrix led and 7-segment led.  The matrices use a driver chip. You can drivers for ultra-bright, consistent color etc, 1/16 step display dimming, all via a simple I2C interface so you can communication with PIC, arduino or any MCU have I2C interface. The address of I2C was selected by jumpers (A0,A1) so you can connect up to four mini matrix led 8×8’s or eight 7-segments (or a combination, such as four mini 8×8’s and four 7-segments,  etc ) on a single I2C bus.

Voltage supply: 3V3
