Open 7400 prize: RGB LED Matrix Backpack from Logos Electromechanical

Logos Electromechanical donated a four-pack of 8×8 RGB LED I2C backpack kit to the Open 7400 Competition. Get your entry in and this and other cool hardware can be yours.

This backpack allows you to drive our 60mm RGB LED Matrix using just a single I2C bus. Not only does this save you the rats nest of wiring required to directly drive a matrix, this backpack has an internal driver that handles all of the multiplexing operations.

Thank you to Logos Electromechanical for sponsoring the 2012 Open 7400 Logic Competition!
