MAX7219 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. Thereon including a B-type BCD encoder chip, multi-channel scanning loop segment word driver, but also a static RAM 8 x 8 for storing each data. Only one external register is used to set the segment current of each LED.

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.

It is a convenient four-wire serial interface can be connected to all common microprocessors. Each data can be addressed without any need to overwrite all displays when updating. The MAX7219 also allows the user to choose whether to encode or not encode each data.

The entire device includes a 150μA low-power shutdown mode, analog and digital brightness control, a scan limit register that allows the user to display 1-8 bits of data, and a detection mode that allows all LEDs to illuminate.

  • 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
