Feature THE BIG BUILD
STEP-07
SOLDER ON THE SWITCH
Make sure the power switch will fit in the hole for it in the case – it’s on
the side of the bottom part. You may need to file away the plastic a bit.
Once that’s done, trim two short bits of wire to about 7 cm long and solder
one to each leg. Solder those to EN and GND – it doesn’t matter which way
around they go.
STEP-08
SHOULDER
BUTTONS
The shoulder buttons (the 12 mm ones) need to
be attached to the controller board much like the
switch was connected to the power board. Clip two
legs off each and use a pair of pliers to flatten the
remaining two. Solder wires to each pin (about 14cm
long) and then solder the other end to the bumper
pins on the controller board. Again, polarity doesn’t
matter, but keep each one as a pair in the row.
STEP-09
WIRE IT
ALL UP
Now we can combine the power
with the controller board, which
will allow us to provide power
to the whole system. Solder two
wires (about 14 cm long) to the
underside of the 5 V and GND pins
on the controller board. The 5 V
wire should then be soldered to the
positive of the PowerBoost board,
with the GND to the negative.
