Now going further on in the guide there are two options
1. The first option is to print flexible PCBs. The advantage is that you save a lot of wiring
business, everything looks rather clean and you dont have to worry about your cables being too
thick such that the casing doesnt close. However if you don't have the means to print out such
business, everything looks rather clean and you don't have to worry about your cables being too
thick such that the casing doesn't close. However, if you don't have the means to print out such
PCBs there is the second option, wiring everything by hand.

firmware is like buying a shoe without measuring your feet before. For this option,
information about the exact firmware is not published, this in addition to the fact that
the pictures in this rough guide are incomplete makes this option extremely
beginner-unfriendly. Going in blind-sided like this may lead to one of these things:
1. reprogramming huge parts of the firmware to match your wiring which comes with a ton of
debugging
2. rewiring to adapt to what the firmware expects, which may easily double your work here

Things to note here:

left to right.
