Overview
Yoga v2 is an open-source printed circuit board by mschwingen, from the mschwingen/hardware repository on GitHub. It is a 2-layer board of 85 × 56 mm with 85 parts on 98 nets, routed with 884 tracks and 99 vias.
It is built around the ADM3202ARUZ, SP385ECA and TPS62932DRL, with the LSF0108PW, 24LC64(LX) and BSS138 among its other parts. Its parts include 20 resistors, 19 capacitors, 9 connectors, 6 ICs and 4 transistors.

README
compensation/README.mdR/C compensation tool
Similar to Analog Devices LB-013, this is a simple R-C-network that is useful when optimizing the loop compensation of switching regulators. I made this to use parts I had around (especially the 5-pin DIP switches), primarily because a nice PCB with silkscreen is a lot prettier than a bit of perfboard.
The PCB with all switches open has ca. 12pF of capacitance.
This is a KiCad design, however, there are PDFs and fabrication-ready gerber files in case you simply want to make your own.

Questions
How big is the Yoga v2 PCB?
It measures 85 × 56 mm and has 2 copper layers, 1.67 mm thick.
What parts does the Yoga v2 use?
85 parts, built around the ADM3202ARUZ, SP385ECA, TPS62932DRL and LSF0108PW. 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 Yoga v2 KiCad files?
From the mschwingen/hardware repository on GitHub, at the commit this page was made from: the board is YOGA_GPIB/yoga_v2.kicad_pcb and its schematic USB-PD-Sniffer/USB-PD-Sniffer_V1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Yoga v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask mschwingen before reusing the design.
