Hi,
That’s massively helpful thank you
So it is possible. You say “The Evolution is to OVAL the Battery Pad Through holes and plated through also. a little bigger is better but not Wider the the Xiao’s PAD” but I’m not too sure what is meant. Is OVAL a technical term or oval as in an ellipse? Also not sure about the “battery pad through holes” they are just pads no? Are you suggesting via in pad for them and if so can I not just route them on the same layer?
I was also wondering if there are any requirements for below the antenna. Should I have this as a “keep out” on the below board?
Thanks again!
