Wiring instructions:
1. On the left block to an input port, an output port on the right.
2. When the control of a single module, simply enter the port received a CPU
3. When more than 3 modules cascaded output input termination CPU, the input output termination module of the first two modules of the first one, the first two modules of the termination input terminal of the three modules, and so on.

Good for a small 8x8 matrix easy to use. Kinda manufacturer each slightly different so one is a bit above another if I tried soldering two together but works well had no problems using this for arduino.

I used these with Arduino nanos to make dugital dice. They are perfect for that because of the low current draw and multiple brightness levels.

Love them, beware you have to solder the pins on yourself (as indicated in the product photos). I liked these so much I bought more.
