The PCBs from Elecrow.com have arrived, and apart from a few cracks/misprints. the majority of them seem to have turned out very well! They are very thin at .8mm, perfect for use in a thin smart watch, and all of the components sit perfectly aligned with each other with great clearance! The only part I don't have now is the imuduinoBTLE, which is still in development but should be completed by the end of this week. Then I'll be able to assemble prototype #1 and test out my first smart watch!
