Questions

How big is the PhotoSensor PCB?

It measures 38.1 × 17.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the PhotoSensor use?

11 parts, built around the TSAL6100 and PT334-6B. 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 PhotoSensor KiCad files?

From the UserHackable/PhotoSensor repository on GitHub, at the commit this page was made from: the board is KiCad/PhotoSensor/PhotoSensor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the PhotoSensor design in my own project?

Its repository states no licence, so its author keeps all rights: ask UserHackable before reusing the design.
