Questions
How big is the Base PCB?
It measures 160 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Base use?
83 parts, built around the THVD1400D, TPS5430DDA, SRV05-4 and XC6206P332MR-G. 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 Base KiCad files?
From the florolf/lab-automation repository on GitHub, at the commit this page was made from: the board is hw/base/main.kicad_pcb and its schematic hw/base/main.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Base design in my own project?
Its repository states no licence, so its author keeps all rights: ask florolf before reusing the design.
