I was waiting for LeandreN's plate to arrive, but it will take a while and I have another 4 PCBs anyway, so I built today the prototype AUNK:
And it was good that this is only a prototype, as I've found a mistake on the PCB. It still works, but need a hack to fit Cherry PCB stabilizers on ANSI layout, and that's unacceptable on the final version.
I also found a mistake on the basic TMK firmware I originally wrote, corrected that in 5 minutes. Now I need to learn how to program layers, and the different kinds of Fn activation.
And that Esc key was asking to be used on this board.
