Version 2 - 36/38-key version

Tempest, version 2

The shape of the pcb has changed slightly in v2:

• optional snap-off pcb for extra key (a la TOTEM) to make 36/38-key layouts
• fixed display connections (currently uses non-standard display pins on the nice!nano, so see the ZMK config for pin details)
• slightly less aggressive middle-column stagger (friendlier for hjkl on vim!)
• fractionally less offset on thumb-cluster for comfort
• improved spacing on mcu to fix collision with inner key column on the top plate

What's Changed

• V2 by @thrly in #9
