Questions

How big is the IR endstop-04 PCB?

It measures 20.5 × 8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the IR endstop-04 use?

11 parts, built around the EE-SX1103, 2N7002K-T1-GE3 and BAT54KFILM. 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 endstop-04 KiCad files?

From the prusa3d/MKxS-IR-sensor repository on GitHub, at the commit this page was made from: the board is rev.04/IR-endstop-04.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the IR endstop-04 design in my own project?

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