Robaux SWT16 User manual

20 Pin Header
Let‘s start with the jack board.
Take the narrow PCB and
solder the 20-pin header to the
back.
1
Assembly Guide
With these assembly instruc-
tions, you can quickly build your
SWT16+. All required compo-
nents are included in this kit.
You need the following tools:
soldering iron, wire cutter, and
solder. Also a desoldering pump
and a nut driver.
Read the instructions carefully
and follow the steps in the cor-
rect order. Robaux wishes you
much fun building the Sweet 16
Plus Sequencer.

Thonkiconns
Now grab the 18 Thonkiconn
Jacks and place them in the
PCB. Please do not solder the
jacks yet!
2
Knurled Nuts
Now put the PCB with the
Jacks on the front panel. Use
the knurrled nuts to tighten the
jacks on the front panel.
If everything is screwed tight,
you can solder on the Jacks.
3

Blue LEDs
Now it‘s up to the LEDs. Let‘s
start with the blue ones. Solder
these in the bottom row. Please
pay attention to the polarity of
the LEDs. The long leg goes
into the + hole, the short leg
into the - hole.
4
White LEDs
That was easy! Then it‘s the
turn of the white LEDs. Solder
these in the two rows above the
blue LEDs.
5

Orange LEDs
Now only the 16 orange LEDs
have to be soldered.
6
40 Pin Headers
Flip the button board over
and solder on the two 40 pin
headers.
7

Keypad
Now place the 4x4 Button Key-
pad and the 4x3 Button Keypad
on the front of the Button
Board. Make sure that the holes
on the keypad match the holes
on the button board.
8
Frame
Now put the frame on the
keypad. Make sure the holes
in the frame match the holes in
the keypad.
9

Screws
Now x the front panel, the
frame, the keypad and the but-
ton board with the four screws.
Insert the screws through all
parts as shown in the picture.
Secure the screws with the
washers and nuts.
10
Power Socket
Now take the main board and
solder the socket as shown in
the picture. Note that the socket
points in the right direction.
11

Pins
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.
12
Diodes
Now solder the sixteen diodes
to the board as shown in the
picture. Please pay attention to
the polarity!
13

Resistor 10K
Now solder the seven 10K
resistors to the board. You
can recognize the resistors by
their color code Brown, Black,
Orange, Gold.
14
Crystal
Now solder the 16MHz crystal
as shown in the picture.
15

Capacitor 220
Now solder the two 220 capa-
citors to the board as shown in
the picture.
16
Capacitor 104
Now solder the two 104 capa-
citors to the board as shown in
the picture.
17

1K Arrays
Solder the fteen 1K resistors
arrays to the board as shown in
the picture. These arrays do not
have a specic direction.
18
10K Arrays
There are even more 10K resis-
tors in the form of two resistor
arrays. Solder the three arrays
as shown in the picture. Please
note that the arrays soldered
in the right direction: the GND
must point upwards.
19

IC Sockets
Now solder the IC sockets to
the board. It is easiest to solder
rst only the outer pins and
then the remaining ones.
20
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.
21

Step Down
Now solder the step-down ad-
apter to the pins as shown
in the picture.
22
Rectier
Now it‘s time for the rectier.
Solder this to the PCB as
shown in the picture. Note that
the - and + symbols on the
board match the symbols on
the rectier.
23

74HC595
Now the ICs can be installed.
Let‘s start with the 74HC595.
Put four of them nose down as
shown in the picture. Two more
are installed with the nose up
on the right side.
24
CD4021
Now you can put the four
CD4021 nose down as shown
in the picture.
25

ATmega
Now insert the ATmega into
the socket. Be sure to attach
it nose down as shown in the
picture.
26
EEPROM
One more IC left. Install it with
the nose down as shown in the
picture.
27

Pins
Insert the pin headers into the
headers on the button board
and the jack board.
28
The last step.
Be especially careful, because
now comes the tricky part! Plug
the mainboard into the installed
pins headers. If everything ts,
solder them on.
Voilà!
Congratulations! Your module
is ready and can be installed in
your case. Make sure the pow-
er cable is plugged in the right
way on both connectors. Enjoy
creating beats with the Robaux
Sweet 16+!
