Questions
How big is the Tof mount PCB?
It measures 40.1 × 45.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tof mount use?
44 parts, built around the CH32V003F4P6, XL1509-5.0, ME6211C28M5G-N and SS14. 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 Tof mount KiCad files?
From the PawprintPrototyping/OpenSauce26 repository on GitHub, at the commit this page was made from: the board is gachapaw/boards/tof_mount/tof_mount.kicad_pcb and its schematic gachapaw/boards/paypi/paypi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tof mount design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
