Questions

How big is the IRBot PCB?

It measures 35.1 × 21 mm and has 2 copper layers, 1.6 mm thick.

What parts does the IRBot use?

49 parts, built around the LM358 and 74HC4067D. 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 IRBot KiCad files?

From the Jannled/InfraLoc repository on GitHub, at the commit this page was made from: the board is ECAD/IRBot/IRBot.kicad_pcb and its schematic ECAD/IRBot/IRBot-Ausschnitt-Doku.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the IRBot design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
