MAX7219 CWG 8-Digital Tube Display Module Control Module

Product details of MAX7219 CWG 8-Digital Tube Display Module Control Module
This is MAX7219 Based Serial 8-Digit 7 Segment LED Display Module. This is also called LED Tube Display. This LED module Arduino has an integrated serial input/output common-cathode display drivers, which connects the microprocessor and 8 digit 7-segment digital LED display. A convenient four-wire serial interface can connect all common microprocessor. From this 7 segment module, each data can be addressed in the update without rewriting all displays. MAX7219 module display also allows the user to select each data encoding or no coding. The 7 segment display module arduino also has a 150µA low-power shutdown mode, analogue and digital brightness control, a scan-limit register allows the user to display 1-8 bit data.

Wiring instructions:（You can pick any IO port, definition can be modified in the program）
1. VCC → 5V.
2. GND → GND.
3. DIN → P00.
4. CS  → P01.
5. CLK → P02.
Notice:
1. VCC and GND Do not reversed, it would burn the chip.
2. 51 MCU P0 port requires pull-up resistor, if your device does not have a pull-up resistor can be connected to other ports data lines.
