README
README.mdHey everyone, As a first venture into pcb making i've decided to make a 60% that is similar to the phantom, as in you just plug it into a Teensy2++, problem is a 60% has no space for a Teensy, so I just ended up with alot of pins which will be hand wired to the Teensy.
The size of the board and all the holes match the GH60, so it should be compatible with all cases.
I am looking for someone to check if my wiring is fine. I am also looking for advice as to how to wire the Teensy, as in which of my pins (p0-p43) connects where. As this is the first pcb a scratched together I would appreciate any and all feedback.

Questions
How big is the Poliboard3 PCB?
It measures 285.8 × 95.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Poliboard3 use?
228 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Poliboard3 KiCad files?
From the Polikon/PoliBoard repository on GitHub, at the commit this page was made from: the board is Poliboard3.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Poliboard3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Polikon before reusing the design.
