a wireless low profile hotswap split keyboard
Dune is a low profile hotswap wireless split keyboard with ZMK support.
I made it because I want to do my homework in my notebook but also be able to type and use my mouse. this way i can place my notebook between the two halves of my keyboard.
Case models are in /Case, case + pcb and just pcb models are both in /Dune.
I'm printing these keycaps for the keyboard.

It measures 278 × 94 mm and has 2 copper layers, 1.6 mm thick.
90 parts, built around the S2B-PH-K-S(LF)(SN) and MK-12C03-G015. 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.
From the ayaangrover/dune repository on GitHub, at the commit this page was made from: the board is Dune/Dune.kicad_pcb and its schematic Dune/Dune.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
