Overview
Explorer Breakout is an open-source printed circuit board by Fraxul, from the Fraxul/Explorer-Breakout repository on GitHub. It is a 4-layer board of 23.1 × 39.5 mm with 6 parts on 21 nets, routed with 652 tracks and 23 vias.
It belongs with the interfaces and adapters boards of this library.
README
README.mdLenovo Explorer cable breakout
This board is designed to replace the captive cable on a Lenovo Explorer Windows Mixed Reality HMD. It was designed for use in an embedded system where the standard 3m cable is too long, but might be useful for other applications. It should also serve as a reference for the pinout of the explorer's data connector (or at least enough of it to get USB3 and HDMI working).
The project has been successfully tested with boards manufactured by Oshpark.
Note: If you have a 3d printer, print the included spacer and install it between the interface board and the motherboard so you don't put strain on the board-to-board connector. 0.2mm layers, 100% infill, no supports. Lay it flat with the pocket facing up.
Known Issues
- The USB3 Type-A connector really should be a Type-C connector (or at least not an upstream-facing A connector!)
- The HDMI connector is too close to the USB3 connector: HDMI cables with large strain relief overmolds will not fit side-by-side with a USB3 plug. I use a slimline HDMI cable for this applcation -- MMonoprice 113578 is known to work.

Questions
How big is the Explorer Breakout PCB?
It measures 23.1 × 39.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Explorer Breakout use?
6 parts. 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 Explorer Breakout KiCad files?
From the Fraxul/Explorer-Breakout repository on GitHub, at the commit this page was made from: the board is Explorer-Breakout.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Explorer Breakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask Fraxul before reusing the design.
