DRAWBAR CONTROLLER D9U
An open-source Do-it-yourself
project base on Ar uino.
MOUNTING INSTRUCTIONS
Welcome to the mounting instruction sheet for the Crumar D9U Drawbar
Controller kit. To assemble this kit correctly an set it up to work
properly, a certain skill with electronics an computers is require , plus
some tools an a little bit of patience an attention.
REQUIRED TOOLS
1. Sol ering iron, preferably a temperature-controlle 60W iron with a
1,5 ~ 2,5 mm wi e tip;
2. Sol er, preferably goo quality 0,8 ~ 1 mm iameter;
3. Goo quality cutters;
4. Phillips screw river;
5. A computer with Ar uino IDE installe .
PREPARATION
Prepare a clean an ti y surface, with just the require tools han y an
make sure you have ischarge your bo y from electrostatic charge by
touching some metal object that makes contact with the floor. Optionally,
wear an ESD wristban .

Electronic parts
Mechanical parts
STEP 1: Let's start from the electronics. All passive components, first,
starting from the lowest till the tallest. Take the four resistors, ben
the terminals 90 egrees an a them to the Main PCB as shown in the
pictures below.
Also a the LEDs, pay attention to the polarity an the posisions. The
shorter lea towar s the e ge of the boar , yellow on the right, re on
the left.
Procee with the sol ering of these first components an cut the excee ing
lea s.
STEP 2: A the angle tactile switch an the mini TRS Jack.
STEP 3: turn the PCB upsi e own an a the 2x8 DIL strip, as shown in
the following picture. Pay attention to have it set straight on the boar
or you'll have troubles when coupling this boar with the rawbar boar .
STEP 4: Take the CPU boar an sol er the SIL terminals to the tiny boar .
This boar contains active SMT electronics an is subject to ESD an
overheat, make sure that your sol ering iron oesn't excee 350 °C
(~660°F) an on't keep the sol ering pin on the terminals for too long.
The SIL strip must face the bottom of the boar , thus the pins will be
sol ere on the top si e, as shown in the picture below.
STEP 5: A the CPU boar to the main boar , as shown in the following
picture. Make sure that the excee ing lea s from the resistors an the
LEDS have been cut as shortest as possible.
STEP 6: Once sol ere the CPU boar , the final assembly shoul look like
the picture below.
Now take your cutters an cut the excee ing terminal strip lea s on the
JACK si e, as shown below. Optionally, you can also cut the excee ing
lea s on the other si e.
STEP 7: Couple the two boar s. The two M3X16 black screws must be set to
the right si e of the rawbar boar as shown here below.
Then, insert the spacers on the other si e, a the main boar an fix the
bolts using your fingers to hol the bolts an a screw river to tighten
the screws.
STEP 8: Use 18 out of the 22 M3X4 black screws to fix the rawbars to the
metal bottom piece, as shown in the picture sequence below.
STEP 9: Fix the PCB assembly to the rawbars an sol er the DIL terminals.
Sli e the boar s slighly angle so the MicroUSB connector can easily pass
through the hole in the metal panel.
STEP 10: Sol er all rawbar terminals an the DIL strip.
