Questions

How big is the Roomba PCB?

It measures 71.8 × 40.1 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Roomba use?

65 parts, built around the ESP32-S3-MINI-1-N8, DRV8411ARTE, TPS562200DDC and SS38. 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 Roomba KiCad files?

From the trhussain/trhussain.github.io repository on GitHub, at the commit this page was made from: the board is boards/roomba/roomba.kicad_pcb and its schematic boards/fan/fan.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Roomba design in my own project?

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