4 Digit Common Cathode 0.5″ – 7 Segment Display Module (Multiplexed)

This 4 Digit 7 segment display project contains 4 x Common Cathode displays, current limiting resistors or each LED segment, 4 x PNP transistors on each common cathode for multiplexing, etc. This is a very compact project that works with 5V TTL signals but can be optimized for 3.3V...
