Overview
Right is an open-source printed circuit board by Hex-4, from the Hex-4/glyph repository on GitHub, published under the MIT licence. It is a 2-layer board of 130 × 109 mm with 49 parts on 62 nets, routed with 309 tracks and 23 vias.
It is built around the COM-09032. Its parts include 24 diodes, 19 switches, 3 capacitors and 2 ICs. It belongs with the keyboards and input boards and the RP2040 boards of this library.

[ a custom split keyboard ]
[ for portably and comfortably interfacing with computing systems ]
Glyph is the keyboard I wish I had. It's a finger-staggered split mechanical keyboard with hotswap support, powered by the Raspberry Pi Pico and KMK QMK firmware. The main gimmick is a joystick next to each thumb switch that acts as a novel way to switch layers, run macros, and navigate documents.
I had made the Hexapad (a macropad) before, but I wanted something to replace my Keychron. It was a pretty nice board, but it had a boring standard layout, non-customizable firmware, and no extra features apart from a per-key white backlight. I saw a video on youtube about someone making their own custom split keyboard, and that planted the seed in my head. When Highway was announced I was sure that this would be my first project. Glyph has a 6x3 main grid on each side, and instead of a vanilla thumb cluster, it has one thumb button and a joystick.

Questions
How big is the Right PCB?
It measures 130 × 109 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Right use?
49 parts, built around the COM-09032. 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 Right KiCad files?
From the Hex-4/glyph repository on GitHub, at the commit this page was made from: the board is PCB/right/right.kicad_pcb and its schematic PCB/left/left.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Right design in my own project?
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).
