Sparkfun Item #: COM-11408 -

"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. Dimensions: 71.6 x 25.7mm Documents:...

"4-digit 7-segment displays are really neat little devices, it’s a shame that they can be so cumbersome to control. Well we’ve solved that problem by making them a little bit “smarter.” The SparkFun 7-Segment Serial Display combines a classic 4-digit 7-segment display and an ATMega328 microcontroller allowing you to control every segment individually using only a few serial lines. The Serial 7-Segment Display can be controlled in one of three ways: Serial TTL...
