MAX7219 Led Dot Matrix Module 8x8 , 8x32 LED Display For Raspberry Arduinos Pi

Description: MAX7219 Led Dot Matrix Module 8x8 , 8x32 LED Display For Raspberry Arduinos Pi The MAX7219 is an integrated serial input/output common cathode display driver that connects a microprocessor to an 8-bit, 7-segment digital LED display, as well as to a line graph display or 64 individual LEDs, and includes an on-chip B-type BCD encoder, multiplexed scanning loops, a segment word driver, and an 8*8 static RAM for storing each piece of data. data. Only one external register is used to set the segment current of each LED. A convenient four-wire serial interface allows connection to a general-purpose microprocessor. The MAX7219 also allows the user to choose to encode or not encode each piece of data. The device includes a 150uA low-power shutdown mode, analogue and digital brightness controls, a scan-limit register that allows the user to display 1-8 bits of data, and a detection mode that allows all the LEDs to be illuminated. Only 3 IO ports are needed to drive 1 dot matrix, the dot matrix display is flicker free and cascading is supported. A single module can drive an 8*8 common cathode lattice Working voltage: 5V Size: 3.2(L)*3.2(W)*1.3(H)cm with 4 screw holes, 3mm hole diameterWith input and output interface, support multiple modules cascade, red, blue, green three colors are optional Note: When the dot matrix and the bottom plate are welded, there will be some unevenness, and there will be skew. Do not shoot if you mind. Instructions for use:1. The left side of the module is the input port, and the right side is the output port2. When controlling a single module, you only need to connect the input port to the CPU3. When multiple modules are cascaded, the input terminal of the first module is connected to the CPU, the output terminal is connected to the input terminal of the second module, the output terminal of the second module is connected to the input terminal of the third module, and so on.Take 51 microcontroller as an example:VCC→5VGND→GNDDIN→P2.0CS→P2.1 CLK→P2.2 A single module can drive an 8*32 common cathode latticeWorking voltage: 5VSize: 12.8(L)*12.8(W)*1.3(H) cmWith 64 fixing screw holes, diameter 3mmWith input and output interface, support multiple modules cascade, red, blue, green three colors are optional Note: When the dot matrix and the bottom plate are welded, there will be some unevenness, and there will be skew.
