Prototypes are meant to be molded and refined until it embodies viable set of features, given the present constraints. Prototyping a device is one thing, but refining it to fit the numerous criteria of technical feasibility, manufacturing, and final product design can be challenging.

That said, we are making very good progress. And these latest images show the device at its 4th iteration in its prototype stage. We are getting close, and all we need to do is to pull all the pieces together to make Monbaby into truly integrated device!

In stead of one big ground pad for the battery you could make 4 smaller pads. In between these 4 pad you can still place traces on the bottom side of the PCB. Put some HASL solder on top of the pads to prevent the battery to actually touch the PCB and there is no risk of making shorts between traces and GND plane by the battery. Because you can’t really rely on the insulation of solder mask.
Thanks for the comment. I’ll take that into account for our next version.
