4-in-1 Display Dot Matrix Module is an integrated serial input/output common-cathode display driver, it connects the microprocessor 7-segment digital LED display with 8 digits, you can also connect a bar graph display or 64 independent LED.

The MAX7219 Dot Led Matrix Module is a serial input common-cathode driver that interfaces micro-controllers to LED matrices. All common micro-controllers 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. Only one external register is used to set the segment current of each LED.

Features :

• Requires only 3 communication wires of MCU

• Pre-cascaded MAX7219 Dot Matrix LED Module.

• The overall size of the display is very compact

• The PCB features M3 holes for mounting.

• Module with input and output interfaces

• Support for cascading multiple modules

• Quite large display
