Questions

How big is the ProcessingUnit PCB?

It measures 150 × 160.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the ProcessingUnit use?

136 parts, built around the VNH5019ATR-E, SN74LVC2G04DBV, BSS138 and AON6354. 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 ProcessingUnit KiCad files?

From the senrobo/open repository on GitHub, at the commit this page was made from: the board is processingUnit/l3.kicad_pcb and its schematic breakout/Cam Adapter/Cam Adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the ProcessingUnit 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).
