Questions
How big is the Main SMD Controller v2 PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Main SMD Controller v2 use?
183 parts, built around the SLG46826G, 74LCX541FT, ADA4510-2ARZ and ADA4522-1ARZ. 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 Main SMD Controller v2 KiCad files?
From the EosinY/ElectronicLoad-AnalogController repository on GitHub, at the commit this page was made from: the board is Main_SMD_Controller_v2.kicad_pcb and its schematic Main_SMD_Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Main SMD Controller v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask EosinY before reusing the design.
