By the way, I've been updating the layout. Most of the changes are relatively minor, shortening some traces, improving clearance, and such.
Today, I made two more significant changes to the mechanical properties: 1) rounded the corners on the antenna side (3.2 mm radius at the PCB edge) 2) added a hole for an optional lanyard or similar. The hole in the PCB is 4.4 mm x 5.4 mm, which means that a channel with an outer size of 4 x 5 mm could pass from the shell through the PCB, yielding an inner opening of 2 x 3 mm (with 1 mm walls). The lanyard channel could also pass outside the PCB, but I kinda like the idea of it holding all the pieces together. I currently estimate the overall thickness of the device at 10.4 mm, so - while not extremely thin - it would still have the kind of thickness of things people hang around their neck. - Werner _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
