Questions
How big is the FloatV2 PCB?
It measures 76.7 × 65.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the FloatV2 use?
38 parts, built around the AO3401A and SS34. 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 FloatV2 KiCad files?
From the murexrobotics/electrical repository on GitHub, at the commit this page was made from: the board is float_carrier_26-27/FloatV2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the FloatV2 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).
