This module is based on the MAX7219 chip which is a compact, serial input common-cathode driver that interfaces microcontrollers to LED matrices.

All common microcontrollers can be connected to this module by using a 4-wire serial interface. Each output can be addressed without refreshing the entire display.

This module requires only 3 I/O lines for driving the display, making it ideal for your microcontroller projects.
