... Can you just use some special cables in place of the small shunts that currently need to be physically moved from the LPF pins to the HPF ones? Is this what you mean by jumper cables? Thanks!

you can replace those red jumpers

with "Arduino Jumper wires"

connected to any SPDT switch (center pin on PCB to center pin on switch)

if you need further assistance feel free to PM me to keep this thread module specific...
