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.
This module should be used with EASY plug control board.
Special Note:
The sensor/module is equiped with the RJ11 6P6C interface, compatible with our keyestudio EASY plug Control Board with RJ11 6P6C interface.
If you have the control board of other brands, it is also equiped with the RJ11 6P6C interface but have different internal line sequence, can not be used compatibly with our sensor/module.
Specification
- Interface: Easy plug
- Supply voltage: 4.5V-5.5V

Connection Diagram
Sample Code
Below is an example code. Open or drag below code to Mixly Blocks and upload.
What You Should See
Upload the code successfully, it will light up a dot light on the matrix.
Extension Experiment 1
Showing 0~5
You can upload the code below to show the number 0~5.
What You Should See
Upload the code successfully, the matrix will show the number from 0 to 5.
Extension Experiment 2
Button Controlled Heart
Hookup Guide
Connect the EASY Plug 8x8 LED Matrix module and button module to control board using RJ11 cables.
Test Code
Below is an example code.
What You Should See
Upload the code successfully, press the button, you can control the matrix show a big heart image or a small one. It seems like a beating heart.
