This 8 Digit Seven Segment Display Module takes advantage of the MAX7219 LED Display Driver IC to allow you to driver its 8 seven segment LED’s using just 3 digital pins. The display removes all the awkward things associated with driving seven segment displays such as multiplexing, refresh rates, current limiting etc. Not only that, headers situated at both ends of the module allow you to daisy-chain multiple modules together to make even longer displays.
