Final board design complete. Build in process
We are happy to share the final board we send out for build. You will notice a few changes. In the center left of the board rests the new solder points for the integrated flex strip. If you remember from previous updates we eliminated the over-molded wiring attaching the earpiece to dongle and designed a waterproof flex circuit. This flex circuit solders to the board at this point. This significantly improves the strength of the connection between the dongle and earpiece and, since the flex strip sandwiches between the main board and battery, further reduces the overall dongle body thickness. Additionally, this flex circuit requires no over-molding and has a really cool look and feel, since it is so thin and flexible. Also you will notice on the left end of the board an integrated battery solder connection. This allows us to eliminate any wiring between the battery and board and solder the battery directly. This reduces thickness and length of the dongle and allows for automated solder of both the battery and the flex strip in one operation. We will keep updating as parts go out and provide photos of the completed parts and final assembly of the first batch very soon.
