EASY plug I2C 8x8 LED Matrix

Introduction

What's better than a single LED? Lots of LEDs! A fun way to make a small display is to use an 8x8 matrix.
This module uses HT16K33 chip to drive an 8x8 dot matrix. Just need to use the I2C communication port of microcontroller to control the dot matrix, which can save more port resources of microcontroller.
The four pin of this module is integrated into a crystal plug. All you need to do is connect the module to control board for communication using an RJ11 cable.
Note: this module should be used with EASY plug control board.
