Yellow 7-segment clock display - 0.56" digit height

Design a clock, timer or counter into your next project using our pretty 4-digit seven-segment display. These bright crisp displays are good for adding numeric output.

E1
Seven-segment LED segment E anode. Adafruit identifies this as a multiplexed common-cathode raw display; the datasheet maps segment E to package pin 1.
Type · segment anodeVoltage · LED segment, Vf/drive current per datasheet; Adafruit notes about 15 mA typical segment drive and up to 20 mA brightest.
