+=== Controller Dual Module x 2 (2 rotary encoders each PCB) ===
This step is a bit tricky. Remember that, if you follow the instructions before, you have soldered the pin-rows in the bottom side of PCBs, so numbering is reversed when looking from bottom. You can use a little trick: if you rotate the PCB 180º, then numbering is "left to right" again ;-)

+'''Note:''' Some encoders have reversed pin ordering, so, if you buy the encoders by yourself, perhaps you have to change A and B pins.
