-
unibody: maybe change physical layout little bit forgot to route r4 silkscreen smaller change hole to 3.2mm (the hole 2.2mm is just for the srcew, not fit m2 standoff) change switch footprint to unreversible (no need reversible in this.) it the rev 0.2
-
for split
- change silkscreen, my cicada look like a fly
- change orientation (angle) of hatched filled zone for aesthetic (rotate keyboard full 8 degree)
- delete jlcjlcjlc, they not gonna use it for order number
