MAX7219-Controlled 4-in-1 LED Dot Matrix Display Module

Description

Operating voltage: 5V
Weight: 55 gm
Fixing screws with 64 holes with a diameter 3mm
Module with input and output interfaces

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.
