Description

This module used an MAX7219 chip to drive an 8 x 8 LED matrix which can be used in various electronic display panels. This module is based on the MAX7219 chip, 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.
