Overview
Fnrow is an open-source printed circuit board by dinofizz, from the dinofizz/fnrow-pcb repository on GitHub. It is a 4-layer board of 328.6 × 38.1 mm with 54 parts on 51 nets, routed with 274 tracks and 26 vias.
It is built around the USB6B1. Its parts include 14 diodes, 14 switches, 7 capacitors, 3 resistors and 3 ICs. It belongs with the keyboards and input boards and the STM32 boards of this library.

FnRow is a mechanical keyboard which features a single row of switches, in the form of a "function row". Each switch is configurable and can be programmed to perform as any key on a typical keyboard, or even combinations of key presses. FnRow is akin to a "macropad", but instead of having a square or rectangular "pad", the switches are stretched out in a single row.

Questions
How big is the Fnrow PCB?
It measures 328.6 × 38.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Fnrow use?
54 parts, built around the USB6B1. 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 Fnrow KiCad files?
From the dinofizz/fnrow-pcb repository on GitHub, at the commit this page was made from: the board is fnrow/fnrow.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fnrow design in my own project?
Its repository states no licence, so its author keeps all rights: ask dinofizz before reusing the design.
