Product information

Description

General description

The MAX7219 Dot Matrix MCU LED 4 in 1 4 x 64 Display Module is an integrated serial I/O common cathode display driver designed to connect with microprocessors, enabling the control of an 8-digit, 7-segment digital LED display, a bar graph display, or 64 independent LEDs. It features a low power shutdown mode and supports cascading multiple modules for expanded display capabilities.

Technical specifications

  • Working voltage: 5V
  • Module size: length 12.8 cm x width 3.2 cm x height 1.3 cm
  • Mounting screw holes: 64 holes with a diameter of 3 mm
  • Power consumption: 150 µA in low power shutdown mode

    • Installation

  • Connect the left side of the module to the input port of the CPU.
  • For cascading multiple modules, connect the output terminal of one module to the input terminal of the next module.
  • Example connections for microcontroller 51: CCV→5V, GND→GND, DIN→P2.2, CS→P2.1, CLK→P2.0.

    • Usage

  • Control a single module using only the input port connected to the CPU.
  • Address each data during updates without overwriting all displays.
  • Adjust segment current for each LED using the external register.
