XIAO BLE 10440 (AAA) adapter for Bastard Keyboard Dactyls

Wireless XIAO Bluetooth holder PCB for Bastard Keyboards TBK Mini and Skeletyl (not tested). Scylla should otherwise work too, but the power switch can't be operated.

Modified from the original Elite-C-holder by Bastard Keyboards, Quentin Lebastard and Alexander Krikun.

It encompasses an AAA battery holder for 3.7V 10440 Li-ion battery. As most of the 10440 Li-ions I found don't have protection circuits built in, I added a protection circuit for the battery based on the reference design of a AP9101CAK6 protection IC.

I have no idea what I'm doing, so this is probably not safe and fine!. Use at your own risk, or better yet, don't use at all. I claim no responsibility of any damage caused by this.

The original Elite C adapter supports Nice!nano and LiPO. Please consider using it instead.
