thanks @htamas... I think I need to talk to @Matt Venn or someone else who knows how TinyTapeout muxes stuff to individual slots. What I'm hoping for is a modified Tinytapeout pad frame that can allow capacitively coupled (to avoid ESD) pins via a direct wire to any 'interested' tinytapeout slots, and then figure out what the upper and lower frequency ranges we can expect to get to the user area
