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 color 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.
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 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. Only one external register is used to set the
segment current of each LED.
