Place and solder the three BAT85 diodes. The (black) band on the
diodes must be at the side of the white band in the PCB silkscreen
(white print on the PCB). Trim the wires.
Place and solder the four 1k
Ω
(brown – black – red) resistors.
Resistors are not polar, so it does not matter in which direction they
are placed, but for aesthetic purposes it makes sense to have them
all point in the same direction. Trim the wires.
Place and solder the six 47
Ω
(yellow - purple – black) resistors.
Resistors are not polar, so it does not matter in which direction they
are placed, but for aesthetic purposes it makes sense to have them
all point in the same direction. Trim the wires.
Place and solder the four 1N5819 diodes. The white band on the
diodes must be at the side of the white band in the PCB silkscreen
(white print on the PCB). Trim the wires.
Place and solder the right-angle pin-header connector. For a good
connection it is recommended to solder both top and bottom sides.
Place and solder the two 100 nF capacitors. Trim the wires.
Place and solder the two PCB sockets. The sockets have a notch at
one end, which should be above the notch in the silkscreen (white
print).
Place and solder the DB9 (female) and DB15 (male) connectors.
Shifting the connectors over the PCB edge might require some
force. There is only one way the two connectors can be places with
each solder cup over a copper field on the PCB.
