Questions
How big is the Beam Alignment Controller PCB?
It measures 70 × 50 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Beam Alignment Controller use?
111 parts, built around the RP2350B, TPS5430DDA, W25Q128JVSIQ and H3V3U10B. 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 Beam Alignment Controller KiCad files?
From the MECSEM/electrical repository on GitHub, at the commit this page was made from: the board is LV-Misc/Beam Alignment Controller/Beam Alignment Controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Beam Alignment 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).
