I've got 4 of these, but need a data sheet to hook them up. Search Google, and every Data Sheet site I know. This is all I could find:
QDS3-W997, 2 VOLTS DC 1mm x 2mm RED AND GREEN CLEAR 40 LED BAR GRAPH-20 RED AND 20 GREEN LEDS MOUNTED ON A 20 PIN IC SOCKET (1/10" SPACING), $15.75
It only has 14 pins, row of 10 on one side, 4 on the other (2 on each end). Not sure what I pulled them from, but had them for years. I was looking for some 10 segment ones (eventually found), but got curious about these, especially after seeing the price
