Kaypaw96
A Southpaw 96% keyboard because numpads on the left are awesome
- They allow the keyboard to be centered on your desk.
- They let you use the mouse and numpad at the same time.
- They are plain more ergonomic.
I made this keyboard because, as an ambidextrous person, I often feel like my left hand is under-utilized while I am doing productivity, coding, and gaming. I also use a 75% and sometimes miss having more keys, so I wanted to make a keyboard that gave you nearly every key of a regular keyboard, plus 4 additional macro keys for things like sleep.

Questions
How big is the Kaypaw96 PCB?
It measures 421.9 × 145.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Kaypaw96 use?
396 parts, built around the RP2040, W25Q128JVSIQ, SK6812MINI-E and ABM8-272-T3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Kaypaw96 KiCad files?
From the Kaympe20/Kaypaw96 repository on GitHub, at the commit this page was made from: the board is pcb/kaypaw96.kicad_pcb and its schematic pcb/kaypaw96.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kaypaw96 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kaympe20 before reusing the design.
