# 5x6 split keyboard
## Checklist
- [x] Setup rev2 project and tidy up usage of footprints and symbols.
- [x] Fix wiring issue between mcu 1 and 2 (VSYS -> VBUS).
- [x] Setup new layout with height differences per finger and tighter spacing (20.5mm -> 18.5mm).
- [x] Create board edge with radius.
- [x] Swap footprint of front mcu + trrs jack to back and the other way around.
- [ ] Find good placement for mcu and trrs that won't require too much height addition.
- [ ] Figure out if aisler can manufacture layout.
- [ ] Draw traces.
- [ ] Re-design footprints so that silkscreen fits on the board and is also on the backside for the reversable ones.
- [ ] Make a decision on how the pcb will be mounted.
## What
I have been using the planck keyboard for 10 years and i find that i usually have to do awkward finger gymnastics to do shortcutr including numbers. This is an attempt at making a keyboard that is easier to use in those situations.
I choose to not have a thumb cluster since i don't find that very ergonomic to me.
## PCB

## 3D models
### Front dampener
This piece sits between the PCB and the switches to dampen the sound of the switches.
