This lovely little (14.2mm) seven segment display provides excellent segment uniformity and is highly visible up to seven meters away. It's ultra bright, and provides great readability even in bright ambient light!

It has four digits and a decimal point on each digit, designed for numeric output, so you can use it to add a clock, timer or counter into your next project.

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.

This is an ultra bright RED colour.
