CREDITS

I've been on the lookout for a unibody keyboard for quite sometime but haven't found one that has all the features I was looking for:

  • Choc V1 spacing
  • Hotswap support
  • Wireless support with an on/off switch
  • Face down MCU mounting
  • 34 keys columnar stagger
  • Only a slight angle but more space inbetween the halves

An established community member in the ergo mechanical keyboard scene by the name of Mabroum heard of my unsuccessful search and took it upon himself to create a board that fullfills all my criterias. He did it in such a record speed that it encouraged me to also try it myself and again delve into the wonderful but for me still daunting tool of Ergogen and KiCad. The board above is the result of that.

I couldn't have done it without the help and inspiration of the lovely keyboard community so many thanks goes out to them. I would also like to thank some individuals that made it all possible

  • Mabroum - for making me a board from scratch and encouraging me to make my own
  • Marco "Bob" - for correctly guessing my firmware error
  • Kilipan "Apfel" - for correctly confirming my firmware error
  • FlatFootFox - for the wonderful introduction/guide to Ergogen
  • duckyb "Kyek" - for the footprints
