Lastly, install J1 and J2
on the back side
of the circuit board.
J1 – Note the orientation of the keying slot before soldering the connector onto the board. Again, the
connector goes on the
back
side of the board.
J2 – Though not a requirement, I’d recommend pulling the center pin out of the J2 connector. If you
leave the pin in place, note that its hole on the PCB is not plated and should not be soldered.
