ITEM NAME:5V MAX7219 LED Matrix MCU Control LED Module For Arduino Raspberry+Line KIOL Descriptio n Material: ABS Color: Random Size: 12.8*3.2*1.3cm Product list: MAX7219 led matrix MCU control LED Display module *1, 20CM DuPont line 5P*1 Module parameters: 1. A single module can drive an 8 * 8 coin lattice 2. Module operating voltage: 5V 3. Module size: Length 12.8 cm X Width 3.2 cm X Height 1.3 cm 4. With 64 fixed screw holes, aperture 3mm 5. Module with input and output interfaces, support multiple modules 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. .. Take 51 MCU as an example: VCC → 5V GND → GND DIN → P2.2 CS → P2.1 CLK → P2.0 High quality buy, happy buyï ¼ MAX7219 Blue led matrix MCU control LED Display module For Arduino Raspberry.Take 51 MCU as an example 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.
