Magic&shell 1PC MAX7219 Dot Matrix Module Microcontroller Module MCU control DIY KIT For Arduino Raspberry Pi

Description: Type: MAX7219 Dot Matrix Module Microcontroller Module DIY Kits. Module Operating voltage: 5 v. Module Size:50x32x13mm/1.97x1.26x0.51Inches(LXWXH). Diameter of Screws:3mm/0.11 Inches. Package Included: 1 PC PCB . 2 PCS 5P Bent Foot Single Row Needle. 1 PC 24P IC socket . 1 PC MAX7219. 1 PC 10uF Ceramic Capacitor. 1 PC 0.1uF Ceramic Capacitor . 1 PC 10K Resistance. 2 PCS 8P Round Hole Seats. 1 PC 3mm 8X8 Total Negative Red Dot Matrix. Wiring instructions: 1. The module left side as an input port and the output port on the right. 2. To control a single module, just connect the input port to the CPU. 3. When cascading multiple modules, the input port of the first module connect to the CPU, the output port connect to the input port of the second one, and so on. In the case of 51 MCU: VCC ¡ú 5V GND ¡ú GND DIN ¡ú P22 CS ¡ú P21 CLK ¡ú P20 Note: 1. VCC and GND is not reversed, it would burn the chip. 2. When the 51 microcontroller P0 port controlling, must be connected to the pull-up resistor, it is recommended that the resistance of 4.7K--10K. 3. Please install lattice into the round hole first, and then insert the round hole to PCB board and weld. Face the side of lattice with words, from left to right pin order is 123456. PCB board 1st pin is square pad. 4.Electrolytic capacitors long-pin as positive, short-pin as negative; ceramic capacitor has no positive and negative points.
