The top and bottom sides of the daughterboard are shown below:
The three pin post pairs are labeled “1”, “2”, and “3” on the top side, corresponding to
the pin number of the SOT23 footprint that the pair connects to. Both posts in the pair
are connected to the same pin.
The user will need to select one of the two possible positions, and one of three possible
rotations, to ensure that the correct pin is connected to the anode signal, and the
correct pin is connected to the cathode signal. The two positions and three rotations
provide six possibilities.
Simple adjust the positioning of the daughterboard until the correct pin number is over
the “ANODE” socket, and the correct pin number is over one of the two possible
“CATHODE” sockets. The choices are summarized in the table below:
Pin post pairs.
