Thanks for writing this, the post is super helpful! I didn't see anything about the circuit design/iteration process. Would be great to hear what software was used to design the circuit (if any) and how that eventually translates to mass production.

The circuit is actually really simple in our case. It is just a voltage converter and then an adapter for the lightning connector.

Getting the custom lightning connector and chip was more of an ordeal though! I'll see what I can dredge up on that process.
