Resources
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.
