8*8 LED Dot Matrix Display Module with MAX7219

The mini 8×8 LED dot matrix display module is based on the compact MAX7219 chip. It is a common-cathode serial input driver that interfaces microcontrollers with LED matrices. All common microcontrollers can be connected to this module using a 4-wire serial interface. Each output can be displayed without refreshing the entire display. This module requires only 3 I/O lines to drive the display, making it ideal for your microcontroller projects.
