1 Digit 7segment 0.56inch Common Cathode

A single-digit seven-segment LED display in the common cathode configuration, where all segment cathodes join to ground and each segment lights when its anode is driven high. This is the arrangement most Arduino tutorials assume, since driving a pin high to light a segment is the intuitive direction. Confirm which type your circuit expects before ordering — common anode and common cathode look identical but wire in opposite ways. Bright, readable digit at 0.56 inch height; Drive segments high to light them, the intuitive direction; Matches most Arduino tutorial wiring; Very low cost for numeric readouts
