5. Preparing of 3pole terminal blocks
Find the terminal blocks, they're grey or blue and come in 3-pin shape. We'll need to slide
two 3-pin blocks together:

7. Solder Jumper J3 (optional :
Perform this step only if you really don't want to use the additional voltage regulator
of the standard kit. If you want to use the USB socket of the Arduino M R for
powering this step is unnecessary also.
Please note:
The supply voltage connected to 9 has to be 5V DC in this case.
Perform the next steps only if you have the standard kit
(includes the parts of the voltage regulator). Otherwise
continue with step 14.
