Oro Link
This is the Oro Link project, a set of custom PCBs, firmware, and server infrastructure for the testing of the Oro Operating System via CI/CD pipelines.
The link is a physical board that interfaces with the ports and headers of supported computers, devices, and boards, and runs firmware to obtain builds of the Oro kernel and associated modules to send to the System Under Test (SUT) for automated testing and reporting.
The Oro Link allows contributors to the Oro project direct access - via pull requests - to test changes directly on real hardware alongside emulated environments, allowing for changes to be tested against niche or problematic hardware configurations.
Project Layout
All PCBs are located in pcb/, where all of the server infrastructure and firmware for the PCBs
is located in firmware/ since it's a workspace with some local dependencies (e.g. the protocol
spoken between the boards and the CI/CD daemon).

Questions
How big is the Sd adapter PCB?
It measures 11 × 45.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sd adapter use?
19 parts, built around the CLM3C-WKW-CXAYA453. 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 Sd adapter KiCad files?
From the oro-os/link repository on GitHub, at the commit this page was made from: the board is pcb/sd-adapter/sd-adapter.kicad_pcb and its schematic pcb/atx24-power/atx24_power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sd adapter 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).
