MAX7219 Led Dot Matrix Module 8x8 , 8x32 LED Display For Pi Arduino VariousProduct Description:
100% Brand New And Good Quality !
Specification:
The MAX7219 is an integrated serial input/output common-cathode display driver that connects a microprocessor with an 8-digit 7-segment digital LED display, a bar graph display, or 64 individual LEDs. It includes an on-chip B-type BCD encoder, multiple scan loops, segment word drivers, and an 8*8 static RAM for storing each data. There is only one external register used to set the segment current for each LED.
A convenient four-wire serial interface can be connected to general-purpose microprocessors. Each data can be addressed when updated without overwriting all displays. The MAX7219 also allows the user to choose to encode or not encode each data. The entire device contains a 150uA 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 makes all LEDs glow. Only 3 IO ports are needed to drive 1 dot matrix, there is no flicker when the dot matrix is displayed, and it supports cascading.
Product parameters:
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 diameter
With 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 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 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→GND
DIN→P2.0
CS→P2.1 CLK→P2.2
