I've bought a display on eBay and made this wiring schematic for it:

the datasheet can be found here

Would be glad if you checked it for any mistakes :roll:

I'd put a 10k pot there between Vcc and ground with wiper going to the contrast connection. Does your module require negative voltage for contrast?

No it doesn't, I've got help from coorz on another forum, my schematic was almost right, just missed one pot. I've soldered it together for 2 days ago, and it works just perfect
