MAX7219 Serial Dot Matrix Display Module

HCOPTO0014

This 8x8 serial dot matrix LED module (HCOPTO0014) allows you to experiment with dot matrix LED's without all the complicated wiring. 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....

This 8x8 serial dot matrix LED module (HCOPTO0014) allows you to experiment with dot matrix LED's without all the complicated wiring. 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. What's more, the modules can be daisy-chained to make larger LED displays whilst still only requiring 3 digital control pins. The PCB has no overhang on the sides of the matrix module so modules can be positioned side by side with no gaps to make one continuous display.



To make controlling this display from an Arduino as simple as possible we have also created an exclusive library which will allow you to display text and numbers and even create a scrolling message display.
