Questions
How big is the LV Controller PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.61 mm thick.
What parts does the LV Controller use?
208 parts, built around the RP2350B, RS485, TPS5430DDA and ADS1115IDGS. 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 LV Controller KiCad files?
From the MECSEM/electrical repository on GitHub, at the commit this page was made from: the board is LV-Misc/LV Controller/LV Controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LV Controller design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
