Version V1.1 is now finished, but I am not happy yet. Since I want to change a few things to have Enlightened Otter as a finished, robust "product", I want to build a second version. :)

The following features should be added/changed:

• Move all parts to the bottom side of the PCB
• Change battery clips from THT to SMD
• Add fuses
• Remove ground-plane around the touch-pads
• Better power plane splitting
• Change ESP footprint to a smaller one
• Add moodlight leds
