Description
This case has modular battery inserts to allow the use of 18350, 18650, and 21700 batteries.
The USB port of the Xiao is accessible, and there are two frames. One with just a power switch to wire inline with the battery, and another which also adds a reset switch.
I used 5mm toggle switch and momentary push button for my build as I find the tactile buttons nice to use, and they are recessed so that you don't accidentally knock them.
There are two panel designs included, and they use M3 screws to hold them in place.
There's spare room to modify the design for things like a GPS antenna which could fit over an 18350 or 18650 battery, and even a Type N antenna connector instead of the default SMA with 8mm hex.
The battery and reset pads are on the bottom of the main Xiao board, so please refer to your documentation to see where to solder the wires.
