MAX7219 8x8 Dot LED Matrix MCU Control Display Module

The MAX7219 is an 8x8 Dot LED Matrix MCU Control Display Module made by Maxim Integrated, supplied in a DIP package. Main ratings: Module size 5 cm X 3.2 cm wide X 1.5 cm high; Module Operating voltage 5V. This page brings together the MAX7219 pinout and key specifications, with the full datasheet PDF to preview below or download.

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. This display module features 8×8 LEDs, 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 LEDs 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 an arrangement, you can connect as many digital dot LED modules to the Arduino as you wish!!! Great.

The MAX7219 matrix module is a 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 LED matrix 7219 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.
