use constant-current drivers for ultra-bright, consistent color (the

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 eight 7-segments (or a combination, such as four
mini 8x8's and four 7-segments, etc) on a single I2C bus.
The product kit comes with:
* A fully tested and assembled LED backpack
* Ultra-bright 4-digit 1.2" tall red seven-segment display
* 5-pin header
A bit of soldering is required to attach the matrix onto the backpack
but its very easy to do and only takes about 5 minutes.
Measurements after you mount the screen:
* 50mm/2" wide
* 120mm/4.7" long
* 13mm/0.5" high
* This board/chip uses I2C 7-bit addresses between 0x70-0x77,
selectable with jumpers.
