For a long time we’ve had small 7-segment displays and huge 7-segment displays, but now we finally have something in between. These 20mm 4-digit 7-segment displays are big enough to see from a distance but not so big that you’d have trouble finding an enclosure for them.

These common-cathode displays feature 4 x 7-segment digits and one decimal point per digit. The LEDs
have a forward voltage of 1.9VDC and a max forward current of 20mA.
