Thank you, PJ, for your time and efforts.
From Point 2
[LiPo SHIM for Pico]
I found this link with the said product you mentioned. Could you please confirm if it’s the same product you mentioned?
And if yes, as you said, this one is for pico board, while you planned to make one for XIAO but never made it, but I should
be able to find the schematics or some design on SEEED somewhere.
I found this link for the above product schematics?>CKT Digram
Does this look correct?
For xiao board itself, do you have any suggestion where can I find that design / schematics that could be suitable for XIAO boards please? Or it can be further inspired from the schematics
I found for pico by suitable modifications?
From point 4
I am trying to analyse battery usage based on product usage approximately, and will come back on that a bit later once I have worked further on it to get your thoughts about it for
suitable battery capacity related inputs.
Further I was also wondering, if I were to just add a simple battery on/off switch on PCB in simplest way will that work for power on/off requirement?
Though it will take up space on the PCB.
Or is there any other better ways that could be simpler for power on/off requirements? Any feedback will be great to have.
Thanks again for your time and support PJ. Highly appreciated.
