Description:

• Size:50mmx32mmx15mm/1.95"x1.25"x0.58"(inch) (approx)
• Module operating voltage: 5V
• A single module can drive an 8 * 8 common cathode lattice
• With four screws hole, aperture 3mm, by using our M3 Tongzhu fixed.
• Module with input and output interfaces, supports multiple modules cascade.

Wiring instructions:

1. The module left as an input port to the output port on the right.
2. The control of a single module, simply input port to the CPU.

Multiple modules cascade input termination CPU, 2 output termination module, a module of the input of the input terminal, the output terminal of the first two modules of the first three modules, and so on ... 51 MCU, for example:

• VCC → 5V
• GND → GND
• DIN → P22
• CS → P21
• CLK → P20

Package List:

• 1x MAX7219 Dot Led Matrix Module MCU LED Display Control Module Kit for Arduino.
• 5x Dupont line.
