Questions
How big is the OsmoIRSensor PCB?
It measures 9.5 × 22 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OsmoIRSensor use?
11 parts, built around the TSOP75436WTR. 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 OsmoIRSensor KiCad files?
From the marelab/OsmoIRSensor repository on GitHub, at the commit this page was made from: the board is hardware/OsmoIRSensor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the OsmoIRSensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask marelab before reusing the design.
