Questions

How big is the Room cleaner PCB?

It measures 90.3 × 123.9 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Room cleaner use?

44 parts, built around the AOZ2262NQI-11, LM2596S-5.0 and HX711. 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 Room cleaner KiCad files?

From the Roguillo/projects repository on GitHub, at the commit this page was made from: the board is room_cleaner/board/board.kicad_pcb and its schematic Power_sensor_hub/Board/Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Room cleaner 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).
