Hi all, after having build my own (first fully DIY) Atreus keyboard, I realize I have a full size keycap set and 120 switches to use and wanted to build a full sized keyboard.
Here I am for now:
It will be wood (4 layers of 3mm each). I still have to check the stabilizer sizes.
I did a wire schema:
33 pins: 12 (blue) + 21 (red)
But I could maybe decrease the number of pins considering the right side (arrow+home/end+numpad) as a continuation of the left row (saving 6 blue pins: 6 blue + 21 reds = 27 pins).
I will maybe need 3 more pins for LED but those are not a priority for now.
So I would need a 30+ pins usb microcontroller.
I used Teensy 2.0 for Atreus but
realized it will not have enough pins (27). Maybe Teensy++ 2.0 (46). Have you any good and cheap microcontrollers that would match my project?
About the firmware, I succeed to use TMK with the Atreus and would use it again for this keyboard. Am I silly? Is there better firmware for full size keyboard?
As it's my first electronic project. Any advise is welcome.
As you can see, it's a lot of question.
A big thanks in advance for your time guys! I'm very excited about this project!
