Introduction: MAX7219 is an integrated serial input/output common-cathode display driver. It connects 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. It includes an on-chip B-type BCD encoder, multiple scan loops, segment word drivers, and an 8*8 static RAM to store each data. There is only one external register used to set the segment current of each LED. A convenient four-wire serial interface can be connected to all general-purpose microprocessors. Each data can be addressed without rewriting all the displays when updating. MAX7219 also allows users to select encoding or not encoding for each data 51 MCU as an example: VCC → 5V GND → GND DIN → P2.2 CS → P2.1 CLK → P2.0Specification: A single module can drive a 8×8 dot matrix common cathode Operating Voltage: 5V Dimensions: 65 x 32 x 13 mm Cable Length: 20cm With 8 fixing screw holes, hole diameter 3mm.
