Overview
Usata is an open-source printed circuit board by ashquarky, from the ashquarky/usata repository on GitHub, published under the CC-BY-SA-4.0 licence. It is a 2-layer board of 20 × 50 mm with 2 parts on 22 nets, routed with 42 tracks and 8 vias.
It is built around the FH28K-28S-0.5SH.
Main components
1README
README.mdusata - connect HDDs and SSDs to your Wii U
usata allows you to remove the optical drive from your Wii U and replace it with a hard drive or solid-state drive. Combined with MLC rebuilding tech you can have up to 2TB of fast, internal storage. The drive also shows up and is usable in linux-wiiu.
Limitations
Your drive must stay within the power limits of the original optical drive - 1.8A@12V, 1A@5V. 3.3V is not connected to maximise compatibility with drives using PWDIS. Since I'm not an expert electrical engineer, the board might not be capable of carrying full power - I would stick to laptop drives or SSDs rather than full-sized spinning disks. If you know how to check the current capacity of the board, please let me know if it's up to scratch!
Manufacturing
I have successfully gotten boards made by PCBWay and JLCPCB in the past. The parts used are the TE Connectivity 2023246-2 and the Hirose FH28K-28S-0.5SH.
You're welcome to make this board, sell it, and remix it as allowed under the license - gerbers are available in the releases section. If you're leaving my name and URL on it, please make sure the version number on the board matches a release.

I'm no expert in PCB design or assembly but I tried my best here. Feel free to file an issue with your thoughts or file a pull request with your improvements.

Questions
How big is the Usata PCB?
It measures 20 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usata use?
2 parts, built around the FH28K-28S-0.5SH. 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 Usata KiCad files?
From the ashquarky/usata repository on GitHub, at the commit this page was made from: the board is usata.kicad_pcb and its schematic usata.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usata design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
