Install the speed control potentiometer in the location marked R2.
This must be inserted fully into the PCB so that the bottom of the
metal bracket is against the PCB. You may need to bend the sides
slightly inward to make it easier to fully seat. Turn the adjusting
shaft fully counter-clockwise.
Locate pushbutton switch S1. Install the switch in the location
marked S1.
Install the two stereo jacks in the locations indicated on the
component side of the PCB. Be sure to press them far enough in to
get them fully seated. There are three plastic “bumps” on the bottom
that will fit into holes in the PCB when they are pushed all the way
in. Install the two threaded, knurled collars on the two stereo jacks.
This keeps them from getting lost! You can use them to mount your
PicoKeyer in a box or tin.
We’re almost there! Find the PicoKeyer chip and remove it from its
protective anti-static package foam. Locate the Pin 1 end – this end
will be marked with a molded notch and/or a dot. If you hold the
chip so you can read the markings on top, Pin 1 is toward your left.
Orientation is important here! Insert the chip into the socket so that
the notch and/or dot on the chip are on the same end as the notch in
the socket and the notch outline on the PCB.
