MAX7219 digital display control module
This module is compatible with 5V and 3.3V micro controllers.
You you can use it for Arduino
MAX7219 is an integrated serial input / output common-cathode display driver,
which connects your microprocessor to a 7-segment digital LED display with 8 digits.
Only three IO ports are used to drive the eight digit display.
MAX7219 supports flicker free displays as well as cascading displays.
Wiring instructions(for example, it can connect any IO port,
modified the Port Definition in the program):
VCC: 5V
GND: GND
DIN: P00
CS: P01
CLK: P02
Note:
VCC and GND should not be connected in reverse or it will damage the chip chip
Specifications:

Shell Color: Blue & black
Net Weight:13g
Jargon buster
Plain-language definitions for the technical terms used above.
- CLK
- CLK is the clock signal that times when SPI data bits are sent and read. A display needs this pin connected correctly so the controller and screen stay in step while data is transferred.
- CS
- CS stands for chip select, a control pin used by SPI devices to tell which connected device should listen. It matters when you connect more than one SPI module to the same microcontroller, because each device usually needs its own CS pin.
- DIN
- DIN means data in, the pin where this display receives data from the controller. Connecting DIN to the correct SPI data output pin is needed for the screen to receive pixel and command information.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
