What do you mean? It does not have pads on both sides.

It may look like the pad could be on the either side from a mechanical point of view when looking at the keyboard. But nothing about the system is designed to handle that (neither firmware, mechanical or electrical).
There also isn't an easy way you could mod the keyboard to have the pads on the other side, so I don't think it's accurate to say there are pads on both sides.

Maybe we could add that note to the mechanical documentation? The only case where you need to know about this, is when you want to build your own module.
But really on the other side of the module there isn't enough space to put a microcontroller and pads 😅

hand side that it can interface with, the module detection expects the
BOARD_ID pin to be connected on the left hand side.
