DAOKAI 7219 Dot Matrix Module 8 x 32 MCU Control Driver Board Green LED Common Cathode 4 in 1 Display Module with Cable for Arduino Microcontroller

Brand: DAOKAI

Color: Green Display Dot Matrix Module

Features:

• Product description: The entire device contains a 150µA low-power shutdown mode, analog and digital brightness controls, a scan limit register that allows the user to display 1-8 bits of data, and a detection mode that turns all LEDs on.
• Specification: Module:Green Display Dot Matrix Module. A single module can drive an 8x8 common cathode lattice, module operating voltage: 5V, module with input and output interface, support for multiple modules cascade.
• Module Features: Modules can be separated, every module comes with its own controller chip.Only 3 IO ports are needed to drive 1 dot matrix, Dot matrix display without flicker, Cascading is supported.
• Wiring instructions: The left side of the module is the input port, and the right side is the output port. When controlling a single module, you only need to connect the input port to the CPU.
• Package includes: You will get 1 x Dot Matrix Module(Green Display), 1 x 5pin Female to Male Cable.

Product description:
The entire device contains a 150µA low-power shutdown mode, analog and digital brightness controls, a scan limit register that allows the user to display 1-8 bits of data, and a detection mode that turns all LEDs on.

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 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 → 5V
GND → GND
DIN → P2.2
Cs → P2.1
CLK → P2.0

Precautions:
· VCC and GND should not be reversed, so as not to burn the chip!
· When using the P0 port of the 51 MCU to control, you need to connect a pull-up resistor, the recommended resistance value is 4.7K--10K

Package includes:
1 x 7219 Dot Matrix Module(Green Display)
1 x 5pin Female to Male Cable

Package Dimensions: 6.6 x 3.9 x 0.8 inches
