🚩 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
🚩 This 8-Digit 7 segment light tube module is compatible of 5V / 3.3V microcontroller; Only three IO ports are used to drive the eight digit display
🚩 MAX7219 LED Display Tube supports flicker free displays as well as cascading displays; PCV board four corners of the fixed copper stud, which can effectively prevent short circuit accidents happen.
🚩 Note:VCC and GND do not reversed, it would burn the chip. 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
🚩 Compatible with Arduino, it requires the Led Control library to be installed – https(:)//github(dot)com/wayoda/LedControl
