Assembly Guide

Assembly Guide
These assembly instructions will help you build your Robaux 3PT.
All necessary components are included in this kit.
You will need the following tools: soldering iron, wire cutter and
solder. Also a desoldering pump and a screwdriver.
Read the instructions carefully and follow the steps in the correct
order. Robaux wishes you lots of fun building the Tripot module.

LEDs
Let‘s start with the LEDs.
Solder the 42 LEDs as shown
in the picture. Please pay
attention to the polarity of the
LEDs. The long leg goes into
the + hole, the short leg goes
into the - hole.
1
Diodes
Now solder the eleven diodes
to the board as shown in the
picture. Please pay attention to
the polarity!
2

Resistor 1K
Now solder the 1K resistor to
the board. You can recognize
the resistor by its color code
brown, black, red, gold.
3
Trimmers
Now insert the nine trimmer as
shown in the picture.
Please do not solder the
trimmers yet!
4

Potentiometer
Now insert the potentiometer as
shown in the picture.
Please do not solder the
potentiometer yet!
5
Thonkiconns
Now grab the four Thonkiconn
Jacks and place them in the
PCB. Please do not solder the
jacks yet!
6

Tact Switch
Now plug in the tact switch.
Please do not solder the
switch yet!
7
Ring
Now take the ring and put it
between the LEDs as shown in
the picture.
8

Panel
Now place the front panel care-
fully on the board.
9
Hex Nut
Fix the potentiometer with the
nut.
10

Knurled Nuts
Use the knurled nuts to tighten
the jacks on the front panel.
When everything is screwed
tight and all components are
aligned, you can solder the
sockets, the trimmers and the
potentiometer.
11
Header 7
Unscrew the nuts and remove
the front panel. If you want you
can now clean the back of your
PCB. Then solder the three
headers to the PCB.
12

Knob
Now put the front panel back
on, screw on the potentiometer
and the sockets. Finally, put the
knob on the potentiometer.
13
Resistor 12K
Take the second PCB. Now
solder the three 12K resistors
to the board. You can recognize
the resistors by their color code
brown, red, orange, gold.
14

Resistor 47K
Now solder the three 47K
resistors to the board. You
can recognize the resistors by
their color code yellow, violet,
orange, gold.
15
Resistor 10K
Now solder the four 10K
resistors to the board. You
can recognize the resistors by
their color code brown, black,
orange, gold.
16

Resistor 1K
Now solder the six 1K resistors
to the board. You can recognize
the resistors by their color code
brown, black, red, gold.
17
Resistor 100
Now solder the seven 100
resistors to the board. You can
recognize the resistors by their
color code brown, black, brown,
gold.
18

Diodes
Now solder the three diodes
to the board as shown in the
picture. Please pay attention to
the polarity!
19
Crystal
Now solder the 16MHz crystal
as shown in the picture.
20

Capacitor 104
Now solder the 104 capacitor
to the board as shown in the
picture.
21
Capacitor 220
Now solder the two 220 capa-
citors to the board as shown in
the picture.
22

Rectier
Now it‘s time for the rectifer.
Solder this to the PCB as
shown in the picture. Note that
the - and + symbols on the
board match the symbols on
the rectifer.
23
IC Socket 28
Now solder the IC sockets to
the board. It is easiest to solder
rst only the outer pins and
then the remaining ones.
24

Capacitors
Now solder the two Electrolytic
Capacitors to the board as
shown in the picture. Please
pay attention to the polarity of
the Capacitors. The red mark
must match the mark on the
PCB.
25
Power Socket
Solder the socket as shown in
the picture. Note that the socket
points in the right direction.
26

Pins 4
Place and solder the Male Pin
Headers as shown in the pictu-
re. It is the shorter pins
of the pin header that you are
soldering.
27
Step Down
Now solder the step-down
adapter as shown in the picture.
28

Pins 7
Now solder the three pin strips.
Tip: temporarily plug this onto
the other PCB so that everyt-
hing is properly aligned.
29
Trimmer 104
If you want you can now clean
the back of this PCB. Then
solder the three trimmers
to the back as shown in the
picture. Turn the trimmers fully
clockwise.
30

DACs
Flip the board over again and
insert the two DACs side by
side as shown in the photo.
Make sure the nose is facing
up.
31
OP Amp
Now insert the amp. Make sure
the nose is facing up.
32

ATMega
Now insert the ATmega into
the socket. Be sure the nose
is facing up as shown in the
picture.
33
Voilà!
Now put the two boards
together and your module is
ready! Please note the instruc-
tions for calibrating the module
in the user manual.
