MAX7219 LED Dot Matrix 4 In 1 Display with 5P Line Module

This is Dot Led
Matrix Module incorporating MAX7219 Driver chip. By using this dot LED
module in your upcoming project,  you will be able to add some great
cool animation.

The individual module features 8×8 LED’s, each controlled very precisely by the MAX7219
driver to generate the colour pattern you wish. The great advantage of
using this is users will have control over all of the 64 LED by just
connecting 3 output communication wires to microcontrollers like Arduino etc.

This product has 4 Dot Matrix LED’s cascaded to form a single LED Display to allot more area to the user on the display.

Connecting the two modules is also very easy. Only connect the output
pins of the previous breakout board to the input pins of the new
module, thus with such arrangement, you can connect as many DOT LED Modules to the Arduino as you wish!!! Great……

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.

Requires only three IO ports can drive a dot! No flashing dot matrix display! Support cascade!
