We were asked if this was possible today, and yes - it is.
Wire your main PedalPCB board as per their diagram, i.e. power connections to the main board, with LED and CLR in-situ.
Wire the connections to our daughterboard as shown, as well as jumpering the CLR pads. Run your jack connections as normal from the daughterboard (not shown so as to keep it neat).
Done.
