7-Segment Display - 4-Digit (White)

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.

We carry this same display in yellow, green, red, and blue.

Core Skill: Electrical Prototyping

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.

3 Electrical Prototyping

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.

    I am a noob but can this fit in a sparkfun redboard

  • Sean Ahrens / about 9 years ago / 1

    Is there a backpack/driver module for this so we don't have to individually connect all segments to digital I/O pins? Takes up a lot of pins.

    The datasheet doesn't say which is pin 1, but it's in the lower left corner. Pin 16 is in the upper left corner.

    Are the resistors built in to the unit for each segment on this?

  • itsjesseyo / about 11 years ago * / 1

    The description is wrong, but the datasheet is correct. 30ish volts.

  • liudr / about 12 years ago / 1

    Does the WRONG spec sheet have the RIGHT pin configuration and dimension?

  • roycohen2013 / about 12 years ago / 1

    Is this visible in sunlight very well?

  • zookeeper9 / about 12 years ago / 1

    Measured voltage of white led segment is 3.0 volts at 20ma.

  • prairie mystic / about 13 years ago / 1

    The datasheet (ATA3492BR) is for a RED led display... White LED's have a much higher forward voltage than 1.9V so the description is wrong. Please fix.
