Questions
How big is the OTlight PCB?
It measures 90 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OTlight use?
86 parts, built around the BME280, LM3478MA, MAX6920AWP+ and TEMT6000X01. 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 OTlight KiCad files?
From the opeRaptor/OTlite repository on GitHub, at the commit this page was made from: the board is oldHardware/OTlight.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the OTlight design in my own project?
Its repository states no licence, so its author keeps all rights: ask opeRaptor before reusing the design.
