Questions

How big is the IR MH sensor-02 PCB?

It measures 42 × 12 mm and has 2 copper layers, 1.6 mm thick.

What parts does the IR MH sensor-02 use?

18 parts, built around the LMV321 and TCRT5000L. 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 IR MH sensor-02 KiCad files?

From the prusa3d/IR-MH-sensor-PCB repository on GitHub, at the commit this page was made from: the board is rev.02/IR-MH-sensor-02.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the IR MH sensor-02 design in my own project?

Its repository states no licence, so its author keeps all rights: ask prusa3d before reusing the design.
