This step is a bit tricky. Depending on your setup it may be useful to solder the 6-pin header row to the back of the PCB, so you can front mount the encoders. In my setup, I bent the 6-pin-row by 90 degrees. The original Zynthian doesn't have this modification, so the pin numbering in the pictures is different!
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 ;-)
So '''you should look at your modules from bottom side and with the pin-row on the top of PCB!'''
'''Looking on the top of the PCB with the 6-pin-row down:'''

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