HI All,
I just received my micro usb lcd backpack and when I was about to start gathering/soldering the parts in I found that there is no documentation on this particular version of it on the site. So I am stuck at the moment.
I can figure out some of the parts, like the status LEDs, filter capacitors, but I am not sure about the rest. Since this is the only panel I got, I don't want to mess it up.
If anyone has a parts layout or list, I would appreciate putting me in the right direction.
For reference, I attached a quick snap of the PCB I received.
Front: [attachment=1]
Back: [attachment=0]
Thanks for all the help!

It looks like the v1b. Here is the partlist for that inhtml format (http://http://code.google.com/p/dangerous-prototypes-open-hardware/source/browse/trunk/LCD_Backpack_PIC_HD44780/hardware/LCD-Backpack-PIC-HD44780-v1b.htm).
You can check out the files there to see which one it looks more like.

Thanks for the quick reply, but I don't think it's the same. I also found this version, but when you look at the board closely you will find some differences, e.g. on the board there is no place for Q1 (the xtal).

Yep, sorry, I guess I've found the right one from the development thread. Here is Ian's post (http://http://dangerousprototypes.com/forum/viewtopic.php?f=19&t=825&start=120#p9532) with schematic & board pictures. Schematic picture has all the values and part names. :)
