Overview
Dboard is an open-source printed circuit board by Croktopus, from the Croktopus/squatterboard repository on GitHub, published under the MIT licence. It is a 2-layer board of 38 × 11 mm with 10 parts on 8 nets, routed with 695 tracks and 12 vias.
It is built around the SRV05-4. Its parts include 3 resistors, 1 capacitor, 1 IC, 1 connector and 1 fuse.

The primary purpose behind this daughterboard is to take up less space "vertically", in addition to using m3 screws (so it can use the same screws I use on the rest of the case) and less screws.
It's also designed to be easily JLC assembled, using basic parts where possible, and the only hand soldering that must be done is the USB and JLC connectors. using the files in the JLC directory, you can get 10 assembled for about $18, though JLC might tack on a $10 "multiple design" tax.
Due to peculiarities of the keyboard i designed this for, it's optimized to be mounted "upside down" with the USB & components on the bottom side, and it's meant to use 1.0mm FR4. Also, the pinout is not at all compatible with the Unified Daughterboard or PCBs which use it.

Questions
How big is the Dboard PCB?
It measures 38 × 11 mm and has 2 copper layers, 1 mm thick.
What parts does the Dboard use?
10 parts, built around the SRV05-4. 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 Dboard KiCad files?
From the Croktopus/squatterboard repository on GitHub, at the commit this page was made from: the board is dboard/dboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dboard 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).
