Topic: 4 Digit 7 Segment LED Display- Pinout help (Read 313 times) previous topic - next topic


I've got a 4 Digit 7 Segment LED Display with a pcb board mounted, and I can't find any information on it.
The different digits, and letters are marked in this order
H G F E D G B A           VCC D1 D2 D3 D4

All of the ones I can find do not have a H, only A-F
Any help would be appreciated!


So can we have the (perfectly focussed, properly zoomed to include the  whole assembly) pictures of this then?


Go on.  A-F probably refer to the standard 7 segments.    H probably referes to the decimal point.
D1-D4 probably refer to the digit selects.

Of course it might be common-anode or common-cathode.    I will not speculate.

You can work this out for yourself with a multimeter.   A link to the Ebay item or a photo is the only way that you will get any worthwhile help.
