Questions
How big is the TofStand PCB?
It measures 179 × 85 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TofStand use?
204 parts, built around the 74LVC2G17GW, SY8120B, USBLC6-4 and BLM21PG221SN1D. 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 TofStand KiCad files?
From the Kreyl/TofStand repository on GitHub, at the commit this page was made from: the board is pcb/TofStand.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TofStand design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kreyl before reusing the design.
