Status: In progress — not released yet.
A board is released only once it has been built, brought up, and verified: it is then listed in PCB/manifest.yaml and ships in the next hardware release (hardware-vX.Y.Z, see the repository's Releases). The model is design decision D10; the release standard is the Releases section of docs/_source/hardware-standards.md.

Questions
How big is the PDU PCB?
It measures 96.6 × 63.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PDU use?
72 parts, built around the SN65HVD230D, AMS1117-3.3, SMBJ12A and SMBJ6.0A. 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 PDU KiCad files?
From the OpenSkyHawk/OpenSkyhawk repository on GitHub, at the commit this page was made from: the board is PCB/Base/Power/PDU/PDU.kicad_pcb and its schematic PCB/Base/Gateway_Bridge/Gateway_Bridge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PDU design in my own project?
Its repository states no licence, so its author keeps all rights: ask OpenSkyHawk before reusing the design.
