MOD-HT16K33 LED 16x8 Matrix Driver Breakout Board

HT16K33 LED 16x8 Matrix Driver Breakout Board

The HT16K33 is a neat little chip that has the ability to drive a multiplexed 16x8 matrix (128 individual LEDs). The communication protocol is I2C so it uses only 2 pins, and can have up to 8 selectable I2C addresses for a total of 8 matrices, each one controlling 16x8 LEDs (1024 total LEDs)

The chip also supports reading a 3x13 keypad matrix (missing library code example).
