I was sent one of these enigmatic boards by mistake, and there was some discussion of it in this forum here

I thought I would work out the identities of all the pads by continuity testing, and I'm posting my findings here in case anyone else finds them useful.

Thanks for the info.

A couple of differences I noticed with the board I have is the J6 K pin and the Nokia GND pin are linked but not connected to ground, I had to ground them myself.

Also the LCD R/W pin is not ground, it is connected to D11, which needs to be programmed as low output.
