Does anyone have the datasheet for this display there is no serial number or Ebay link. A student came to me with this 4 digit 7 segment LED, there are 12 pins in one side, and nothing on the other side. Model number is, WP02841MGA.

    Send the aforementioned student to search for the datasheet. He might learn that a component without a datasheet is junk. – Nick Alexeev Apr 29 '15 at 18:00

    The part number is right there. It's probably a custom ordered part, just look for similar part numbers. – Passerby Apr 29 '15 at 18:08

    Just search for similar part with same pin configuration. Many are pin compatible. Use a multimeter with a diode test to make sure. In case of internal series resistors, use a ohmmeter and a laboratory power supply and light the LEDs up. – FRob Apr 29 '15 at 18:27
  • Nick Alexeev it's a cute kid right :D ! Passerby " It's probably a custom ordered part" exactly you can't found anything with that number. FRob i search allot, all what i found is 6 legs in each side, there is no 12 legs in one side Spehro Pefhany that's exactly what i will do :) Passerby ok thanks for you too – narzan Apr 29 '15 at 19:06

If you just want the pinout, poke around with a 5V supply with a 1k resistor in series and in minutes you'll have it.

With 12 pins it's a multiplexed display with at least four commons. Could be common anode or common cathode, some of the positions (colon, some or all decimal points) may not be populated.
