I regret to inform you that I am not competent to make electrical systems design changes on a device like this.

This is the perfect thing to learn on. It's actually a very simple thing as these things go. I expect there would be just a few changes needed, typically the components used in these things are friendly to this need and you just need to reconfigure them a bit or order a slightly different part number for a few components.

God speed

You know, if this was software, I would agree with you.

Let’s just say that hardware and I are not a good fit.
