1.3 Technical aids and tools
At the ARTC- assembly kit a few solder- and mounting steps are necessary. Following
tools and technical aids are needed for the finishing only:
1. Solder (Ø 0,5 mm – 1 mm)
2. Desoldering wick (optional)
3. Cross recess screw driver
Furthermore it is needed a soldering iron to solder the last component the Lithium-
Battery.

1.4 Important information!
Please consider always the assembly- and safety instructions of the
manual in further process, which are signed with the yellow
warnings sign.
•Always use the the recommended tools and technical aids for the preparation- and
assembly steps.
•Before you are forming, soldering, assembling or changing the components in any
other way, please be sure that the steps of the construction manual are completely
read and understood.
•Please do all soldering, forming and wiring conscientiously. The result will pay your
effort!
•And please read too the safety information in the PiXtend data sheet and the
printed safety instructions, which are included in the assembly kit.

2. Final assembly
The final assembly is done in a few steps with the ARTC-assembly kit. Nevertheless we
want you to take care about the following assembly steps.
Then there are no more obstacles to start with your project with PiXtend and Raspberry Pi!
Which components are getting places on which position you can see in the placement plan
on the following page. Print out the placement plan and the part list on page 6 for
comfortable and failure free working.

2.1 Montage of the integrated circuits (ICs)
The integrated circuits (ICs) have to be mounted on the PiXtend- board. For an easy and
unproblematic mounting the pins should be bent before.
The “feet” are standing not exactly straight down, how you can see in Figure 4 (left). The
pastic housing and then getting pressed against a hard surface until the wanted angel is
reached. Like that all Pins of each IC are getting bent equally.
After bending the pins should have an angel of 90° to the plastic housing, how you can see
in Figure 4 (right).
When mounting the prepared ICs it is to care for the notch, same as at the montage of the
IC sockets.
The notch of the IC, IC socket and the printing on the board
have to match.
If the ICs are getting mounted wrong it can lead to malfunction
and defects!

Some Chips have no notch, they have a point. Picture 6 shows the correct positioning.

2.2 Battery
Now it is time to mount and solder the Lithium-Battery on the circuit board.
The battery is supplying the real time clock with power, when the PiXtend system is
switched off. This is important that the system still has the right time and date after
switching on the Raspberry Pi.
Stick the battery in the intended holes of the circuit board. The component has on one side
two, and on the other side only one solder tail. Because of it is not possible to plug it with
switched polarity.
As next the circuit board has to be turned and the battery hold that it doesn't fall out.
Now the component can be soldered on the bottom side. For now solder only one pin, so
the battery can be adjusted. The Battery should neatly lie on the board ( especially
important if later the PiXtend- stainless steal housing is getting mounted).
After the adjusting the rest of the pins can be soldered.
The result after the soldering is showing figure 7.

2.3 Spacers and screw joints
In the assembly kit are different spacers included (M3 and M2.5).
On the outer edge of the circuit board are all together eight drills. Here we need the M3.5
mm spacers with external thread and the M3x15 mm spacers.
Order from left to right (Figure 8):
M3x5 mm – circuit board – M3x15 mm spacers
In the middle of the circuit board are six more drills. Four of them are used for the montage
of the Raspberry Pi model B+ / 2 B / 3 B. The rest of the drills are normally not used (they
are for the montage of the “old” Raspberry Pi model B (without “+” or “2” / “3”).
Hold the Raspberry Pi over the board before the montage, so it is easier to see which drills
are the right ones.
The order here is the same as with the M3- spacers:
M2.5x5 mm – circuit board – M2.5x25 mm spacers

2.4 Rotation axes
The both rotation axes can be easily put in the for it marked positions of the Potentiometer
R60 and R62 without any tools.
ven when it functionally makes no different do we recommend to put the “arrows” in the
rotation axes in the same orientation. That helps at adjusting the analogue outputs later.

2.5 Jumper
As last step before the connection of the Raspberry Pi with the PiXtend the Jumpers are
getting set.
To the pin headers / jumpers on the PiXtend we want to give you the most important
information:
–Jumper "SPI_EN":
→ The most important jumper! For standard operation this one has to be placed
all time. Without this jumper the Raspberry and the PiXtend can't communicate.
–Jumper next to RS485- or CAN-clamps with the labeling „ON OFF“:
→ The position of this jumper will be important when the interfaces are getting
used. More information you can find in the datasheet of PiXtend. For now set the
jumper to the position “OFF”.

Figure 10: Jumper "SPI_ N"

PiXtend
Construction manual: PiXtend V1.3 ARTC
Kit Assembly
–Jumper „DO-PWM“ near DO4 and DO5:
→ In the first step the jumpers are getting set to the middle and the left pin (position
“DO”). Which effect the setting of this jumper has you too will find out in the
datasheet.
–Jumper „+5 _PI“ / „ON OFF“ next to the 26poligen tub connector:
→ With this jumper is getting decided if the 5V supply of the PiXtend will be used or
not. If you connect only one power supply to the PiXtend and the Raspberry Pi
should have no extra supply so this jumper has to be set to “ON”. More infos you
find in the datasheet!
–Warning!
–If the jumper “5V_PI” is at position “ON”, then it is not allowed to
connect another power supply to the Raspberry Pi.
–The possible compensation currents between the both power
supply units can lead to malfunction, overheating of
components or even the defect of them!
–Pin header „I²C 5 “ / „SDA SCL“:
→ Is not thought for setting jumpers! Here you can devices be connected to the
I²C-bus. Don't set jumpers!
–Jumper „10 5 “ (analogue inputs) and „5 24 “ (digital inputs)
→ Should in first step be set to “24V” at the digital inputs and to “10V” at the
analogue inputs. Here can be changed the input voltage later if needed.
–If you are not sure at setting the jumpers, so it is always the safest to not set the
jumper. More information to the jumpers and there effects you can find in the
PiXtend data sheet.

In the initial operation manual you are getting reminded to check the position of the
components. At the transport of the assembly kit sometimes it can happen that a
components is getting bent that it is touching another component.
If this is recognized early (before the first operation) it is no problem. You can make this
check at this point too, before you are mounting the Raspberry Pi and restrict the view.
Your PiXtend now is ready for the “marriage” with the Raspberry Pi Model 2 B.
The following steps are valid equally to the model 3 B / B+.
