This is the version of the watch that uses a discrete IMU, pressure sensor, and voltage regulator. It will fit into the iPod nano case but is more difficult to solder. It has also replaced the rocker navigation switch with 3 small pushbuttons. In addition, this includes a board mounted piezo speaker.

How did you solder those small DFN parts?
ReplyDeleteSorry for the delay. I actually used a soldering iron for the Mega chip. With a lot of flux, it is pretty easy. The small sensors, I tinned both the board and the component, placed the component in place, and used a reflow hot air gun until I saw the part sink flush. I was amazed at how easy it was and I didn't have to mess with paste and stencils.
