What will happen if I make a cutout in my PCB for the bottom components in the middle of T4 and use pads instead of the castellated cutouts?
Then I'll put it in one of these: https://www.amazon.com/Happybuy-Infr...3596831&sr=8-2
Will all the good things fall off of the poor Teensy or will they hold?
What if I use the low temperature paste?

If it works, it will be much cheaper and easier than the castellated cutouts which nobody makes or charge a fortune.

Did anybody try that?
I really need the SD pads, the USB host and all those bottom pads.
