Now you need to join the two boards together. You have a nice 6-way ribbon cable, right? If not, just
run six lengths of wire between the two boards. The pads are clearly marked, just join like for like.
Now attach some decent lengths of wire to the rest of the offboard pads - your V and G connections
at the top of the board, and your jack connections on the daughterboard. Ignore those LEDS again -
they aren’t really there...
