Parasit Relay Board

[SYLV9ST9R]

I have a couple of these Parasit Relay Board on hand.
How would I hook them up to PPCB boards?
I’m guessing Send to board In and Return to board Out, but what do I do about the GND and SW pads, and the LED pad on the board (leave them alone, jumper, ??)?

That is correct. To make things simple I would probably run your LED from this board and omit it from the PPCB board. Just leave those pads on the PPCB board empty

What I (kinda) thought, thanks for confirming.
