I am extremely careful. I triple checked from all sides and especially from the *underside* and there are no pins visible. I tried to take a picture yesterday and today in good daylight, with and without camera flash, with and without additional lighting but I can't get a usable picture *between* the PCBs. I wish you could see through my eyes :) I think we have to trust in my assessment.

Worked... almost like... *magic*.

It is kind of obvious but still nice when explicitly mentioned. :) So the next and last step hardware wise is to solder the UART connection to the micro desktop? Can I use standard pin headers? kind regards Pablo _______________________________________________ arm-netbook mailing list arm-netbook@lists.phcomp.co.uk http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to arm-netb...@files.phcomp.co.uk
