Dot Matrix Control Module LED Single Chip Microcomputer Controller 4‑in‑1

<div>Welcome to our store! We hope you have a wonderful shopping experience!</div>

<ul><li>Feature: 
1. It is an integrated serial input/output common cathode display driver 
2. This module is connected to a microprocessor and an 8‑digit 7‑segment digital LED display. It can also be connected to a bar graph display or 64 independent LEDs. 
3. The module includes an on-chip B-type BCD encoder, multi-channel scanning loop, segment word driver, and an 8 x 8 static RAM for storing each data. 
4. Each data can be addressed. No need to rewrite all the display when updating, it also allows the user to choose to encode or not to encode each data. 
5. The entire device includes a 150μA low-power shutdown mode, analog and digital brightness control, a scan limit register that allows users to display 1-8 bits of data, and a detection mode that allows all LEDs to emit light. 
6. Only 3 IO ports are needed to drive 1 dot matrix, no flicker when dot matrix display, support cascading 
Specification: 
Item Type: Dot Matrix Control ModuleMaterial: Synthetic CardboardA single module can drive an 8 x 8 common negative dot matrix 
Module Working Voltage: DC5V 
Fixing Screw Holes: 64 
Hole Diameter: Approx.3mm / 0.1in 
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, 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 Microcontroller as Example: 
VCC → 5V 
GND → GND 
DIN → P2.2 
CS → P2.1 
CLK → P2.0. 
Package List: 
1 x Dot Matrix Control Module1 x 5 Pin Cable</li></ul>
