Thank you.
Where did you find josh cook’s github? i got an error 404 when i tried to find him.
And how did you do that now? Is there a turtorial for such things? How long did you need for that now? Do you think, with zero PCB-design-knowledge someone could be able to try the same (just for learning) in some hours? Or is that a thing of long learning process and knowledge of electrical stuff?
What do you mean by pinout? Where did you find the pinout for the 4i? maybe i can help searching.
