The MAX7219 is an integrated serial input/output common-cathode display driver that connects a microprocessor to an 8-bit digital 7-segment LED display, or a bar graph display or 64 separate LEDs. It includes an on-chip B-type BCD encoder, multi-channel scan loop, segment word driver, and an 8*8 static RAM to store each data. Only one external register is used to set the segment current of each LED.

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 150A 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.

Only need 3 IO ports to drive 1 dot matrix! No flicker when the dot matrix is displayed! Support cascading!

Module parameters:

1. A single module can drive an 8*8 common cathode matrix

2. Module working voltage: 5V

3. Module size: length 13 cm X width 6.4 cm X height 1.3 cm

4. With 32 fixing screw holes, aperture 3mm

5. Module with input and output interface, support multiple module cascade

Wiring instructions:

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 of the first module is connected to the CPU, the output is connected to the input of the second module, the output of the second module is connected to the input of the third module, and so on. ..
