8x8 Led Matrix Schematic. The module makes use of the max7219 serial matrix led driver which handles all the complicated stuff such as multiplexing the leds and driving them at the correct currents. You can build 8 of these led matrix modules but connect the long sides together to form into an 8x8x8 led cube like our jollicube.
The module makes use of the max7219 serial matrix led driver which handles all the complicated stuff such as multiplexing the leds and driving them at the correct currents. 8x8 led matrix pin configuration led matrix modules are available in different modules and each module will have different pin configuration. We will be building this arrangement of common row cathode matrix in this tutorial.
If you are interested you may check out our jollicube instructable here.
We will be building this arrangement of common row cathode matrix in this tutorial. It has 24 12x12 pins but no way for me to tell which one is pin 1. The parts to build this matrix we will need a few things to get us started. There is a led for each pixel and these leds are connected to total of 16 pins.
