Pteron36 finalized

The design of Pteron36, an open source 36 key split keyboard by smart345bond, is finalized.

The Pteron36 was already announced and featured in KBD. However, smart345bond kept working on the design which is now declared finished.


I have been using Lily58 as my daily for a some time, but my thumb and pinky were very cramped and I did not like the feel of those two. I wanted the inner most thumb key to be moved out, and the arc of thumb cluster to be more natural.

I found the original Pteron by FSund, and I knew it is exactly what I was looking for. So I modified the PCB files of Kraken-Jokes to make this board.
