Adafruit Small 1.2 8x8 LED Matrix w/I2C Backpack - Yellow-Green

Description

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, consistent 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. These 1.2 matrix backpacks come with three address-selection jumpers so you can connect up to eight 1.2 8x8's together or a combination, such as four 1.2 8x8's and four 7-segments, etc on a single I2C bus.

 
The product kit comes with:

• A fully tested and assembled 1.2 LED backpack
• Ultra-bright 1.2 8x8 green matrix
• 4-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.
