This is a basic, 4-digit 7-segment display - white in color. It has a common anode. The display features one decimal point per digit, and individually controllable apostrophe and colon points.
The LEDs have a forward voltage of 1.9VDC and a max forward current of 20mA. The hardware interface is sixteen (two rows of eight) through-hole pins
The datasheet for this device says “blue” but that’s because the white display is simply a blue display with a colored film over it.
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.
