From the project
An Open Source keyboard designed for Kailh Low Profile Switches
This keyboard is meant to be ultra portable, using the Kailh Low Profile switches and a minimalist design. That being said, I wanted to add all the keys that I miss when typing on my 40% and 60% boards, such as arrow keys, Home, End, Delete, Up and Down. I also decided to use USB C as the connector, since I perfer the form factor and flexablility for future designs. The keyboard will be fully customizable through QMK, the software of which will be coming up soon.
