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.
