Product Description
MAX7219 Dot Matrix Module Microcontroller LED Display Module 4 In One Display 8x8 Control Single Chip Microcomputer Module with 5P Line 5V for Arduino DIY
Feature:
1.Unmatched Display Precision: Our dot matrix module is equipped with the MAX7219 display driver, enabling a  interface between your microcontroller and an 8-bit 7-segment LED display. The versatility extends to bar graphs or an array of up to 64 LEDs, offering a variety of display configurations for your project needs.
2.Effortless Communication: The MAX7219 promotes easy interaction with our microcontroller module through a four-wire serial interface. It grants individual data addressing, allowing quick refreshes of any segment without overhauling the whole display, optimizing the update process.
3.Adaptable Design Capabilities: The MAX7219's inclusion of an on-chip B-type BCD encoder, multiple scanning circuits, and segment drivers, along with an 8x8 static RAM, forms the core of our microcontroller LED display module. External segment current configuration adds a layer of adaptability for LED intensity, matching specific project demands.
4.Energy-Saving Operation: Our control single chip microcomputer module showcases the MAX7219's power-efficient design, including a low-power shutdown mode that only uses 150μA. Its dual brightness control modes, both analog and digital, empower you to alter the intensity for optimal power consumption and visibility.
5.Expanded Display Creativity: The MAX7219's capabilities reach new heights with our LED matrix display module, as it only requires three I/O ports to manage a single matrix. This cascading feature invites the linking of multiple units to design expansive and intricate displays, ensuring a smooth, flicker-free visual presentation.







 

Specification:
A single module can drive an 8*8 Common Cathode
Module operating voltage: 5V
Module size: 128mm*32mm*13mm/5.03*1.25*0.51''
Display: Red
With 64 fixed screw holes, aperture 3 mm
Modules with input and output interfaces support multiple modules cascade
Packaging weight: 49g

Wiring Description:
1. The left side of the module is the input port, and the right side is the output port.
2. When controlling a single module, you only need to connect the input port to the CPU.3. When multiple modules are cascaded, the input end of the first module is connected to the CPU, the output end is connected to the input end of the second module, and the output end of the second module is connected to the input end of the third module, and so on.
Take 51 MCU as an example:
VCC-5V
GND-GND
DIN-P2.2
CS-P2.1
CLK-P2.0

Note:
Please allow 1-3mm differs due to manual measurement.
Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understanding.
