Yellow 7-segment clock display - 1.2" digit height

The Large 4-Digit Seven-Segment Display gives your project bright yellow numeric output for clocks, timers, counters, and readouts, with colon dots and an extra indicator dot built in.

I like big seven-segment displays and I cannot lie! Design a clock, timer or counter into your next project using our pretty, candy-bar sized 4-digit seven-segment display. These bright crisp displays are good for adding numeric output. Besides the four 7-segments, there is a top right dot (perhaps useful as a degrees symbol) and two sets of colon-dots (good for time-based projects). These are ultra 36mcd bright per segment. Each segment is made of two LEDs in series for even colouring (check the datasheet for a diagram). You can drive these with less current to get the same brightness to save power, or crank them up to 20mA and have them at their brightest. These displays are multiplexed, common-cathode. What that means it that you can use a 74HC595 or just 8 microcontroller pins if you can spare them to control the 8 anodes (7-seg + decimal) at about ~15mA each, and then connect NPN transistors or a TPIC6B595 to the cathodes to sink the 8*20mA = ~120mA maximum per digit. We strongly recommend getting our backpack version, which comes with an LED driver on the back. This version is just the raw display, and requires a lot more work to get running! These come in a bright yellow colour, we also have many other sizes and colours!
