Output Jack (±)
Your kit came with either ¼ inch or 3.5 mm jacks like the ones shown below. Refer to the diagram below. Make sure
that the right pins on the jack are connected to the correct holes in the PCB. The round pad is the ground and
connects to the shield lug on the jack. The square pad is the signal and connects to the tip lug.
If you are have ¼ inch open frame jacks, look carefully at which lug is connected to which contact, because not all
open frame jacks are the same. If you have ¼ inch closed frame jacks that are switched, then there are six terminals
on the jack, so make sure that it is oriented as shown. If you connect the wires to the switched terminals, then
nothing will happen when you plug in the jack.
Trigger Jack (±)
Just as with the output jack, make sure that the right pins on the jack are connected to the correct holes in the PCB.
Again, round pad is shield and square pad is tip.
Module Power (±)
If your Thunderclap is a Eurorack module, then solder the supplied 10 pin header in place. Make sure that it is flush
with the PCB. Connect the module to your power bus as you would any other module. That is, with the red stripe of
the power cable facing down.
If your Thunderclap is non-Eurorack module (with a different type of power connector), you will have to solder wires
from your power connector directly to the PCB. Only the V+ and GND connections are used. The V- connection is
not used.
