“8 Digit 7 Segment MAX7219 Module is an amalgamation of two pieces of 0.56” 4 Display 7 Segment Common Cathode Module which is mounted or arranged horizontally and controlled by MAX7219 driver. The advantages of this module is that it only takes 3 pins of I/O as a communication on arduino, so as to minimize the use of arduino I/O pins. This module can be applied to various projects that require character display, especially numeric characters, for example: Digital Clock Project.”
