symmetry78

A rearranged handwired 75% keyboard powered by QMK Firmware. This has not been merged with the master branch of QMK as of yet.

Function row, navigation cluster and arrow keys found on a typical 75% keyboard arrangement have been moved as macro columns to the left and right of the alphas and modifiers for better symmetry.

Current layers contain:

  • (0) - Standard QWERTY Layout (Caps Lock has been remapped to Ctrl)
  • (1) - Typical 60% Function row location on the alpha numbers, Volume controls on R/L arrows, PgUp/Pgdn on Home/End, Caps Lock restored, plus a TT(2) on F2.
  • (2) - DVORAK Layout (Caps Lock has been remapped to Ctrl)
  • (3) - Same as (1), plus a TO(0) on F2.

Current pinouts are making use of an Elite-C.

BOM for the build:

Mandatory things:

  • 78 x MX style switches
