Overview
Adapter is an open-source printed circuit board by strfry, from the strfry/LG360VR repository on GitHub. It is a 4-layer board of 45.5 × 50 mm with 58 parts on 83 nets, routed with 682 tracks and 103 vias.
It is built around the LD1117S33TR(MS), MH2029-300Y and IRLML2244TRPBF. Its parts include 19 resistors, 18 capacitors, 5 connectors, 3 ICs and 2 switches. It belongs with the interfaces and adapters boards and the STM32 boards of this library.

README
README.mdSummary
This about making the LG 360 VR Goggles usable with a normal DisplayPort outlet.
The LG360VR uses the "DisplayPort over USB-C" standard. Our assumption is, that with little hardware effort, we can send a DisplayPort signal into it.
Current State of things
- A passive PCB Adapter has been manufactured, though it doesn't work
Currently in the process of analyzing USB-PD communication, to figure out if this is the problem- Resolution: USB-PD Handshake is definitely necessary to get a display connection
- Now designing a new PCB with STM32F072 for PD Handshake and DisplayPort Redriver IC

Questions
How big is the Adapter PCB?
It measures 45.5 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Adapter use?
58 parts, built around the LD1117S33TR(MS), MH2029-300Y and IRLML2244TRPBF. 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 Adapter KiCad files?
From the strfry/LG360VR repository on GitHub, at the commit this page was made from: the board is adapter/Adapter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Adapter design in my own project?
Its repository states no licence, so its author keeps all rights: ask strfry before reusing the design.
