Features
- Uses the RP2040 MCU, with ZD25Q80BNIGR (1 MB of external flash).
- Uses Kailh MX hotswap sockets.
- Added anti-shearing to the hotswap sockets.
- Holes of hotswap socket holes are plated, you can still solder in a switch, should a hotswap socket ever shear off for whatever reason.
- 65% layout (see below).
- Support 5 UDB positions.
- Support RGB Matrix, with 2 IS31FL3729 LED drivers and MHT151RGBCT LED per-keys.
- Has cutout for gummy o-ring mount (Bakeneko65, ...) and other mount.
- Physical BOOT button for getting into bootloader if bootmagic isn't available. Acessible under PCB.
- SWD header for debugging.
- ESD chip (SRV05-4) to prevent damage from electrostatic discharge.
- Polyfuse to prevent overcurrent.
- Optimized for manufacturing and assembly with JLCPCB.
- Bonus: Curved traces and teardrops.

Questions
How big is the Nyx PCB?
It measures 304.3 × 108.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nyx use?
316 parts, built around the RP2040, 74LVC1G17Z, W25Q128JVSIQ and 1N4148W. 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 Nyx KiCad files?
From the HorrorTroll/Nyx repository on GitHub, at the commit this page was made from: the board is pcb/rev1/nyx.kicad_pcb and its schematic pcb/rev1/nyx.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nyx design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
