Questions
How big is the Vr trackers PCB?
It measures 30 × 30 mm and has 4 copper layers, 1.62 mm thick.
What parts does the Vr trackers use?
67 parts, built around the TPS61254YFFR, MAX40203AUK+T, MAX17048G+T10 and XL7EL89COI-111YLC-32M. 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 Vr trackers KiCad files?
From the 1vers1on/vr_trackers repository on GitHub, at the commit this page was made from: the board is vr_trackers.kicad_pcb and its schematic swd_adapter/swd_adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vr trackers design in my own project?
Its repository states no licence, so its author keeps all rights: ask 1vers1on before reusing the design.
