Do you have the board? Is there an ident marked on it?

It looks like there might be  but, in the photo, it's obscured by the capacitor:

Failing that, look at the Gerbers and/or CAD files: see which pin is GND - you can get the rest from that

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

And the Gerbers are here:

also CAD design files

Thank you for quick answer, however I need to know if the pin no.1 is closest to the capacitor or the oposite one.
