This is a 75% mechanical keyboard that has per-key rgb, hotswappable keys, an OLED, and a rotary encoder. It's based on the Raspberry Pi Pico so it supports QMK and KMK.
I decided to make this because I love mechanical keyboards but the one I was using broke. And keebs over here just don't got much variety or they are low quality, so I decided to make my own.
- Open Source
- Hotswappable
- Per-key SK6812MINI-E RGB Backlight
- A rotary encoder
- 75% Layout
- 0.91" Vertical OLED
- Easy to program (depends from person to person)
- QMK and KMK both are supported
- 3D Printed / CNC Case and plate
