Questions
How big is the LoadController PCB?
It measures 140 × 85 mm and has 4 copper layers, 2 mm thick.
What parts does the LoadController use?
84 parts, built around the LTC7001IMSE#PBF, ACS758LCB-100B-PFF-T, BAT54S and SMBJ33A. 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 LoadController KiCad files?
From the DanielPopa1109/ELC repository on GitHub, at the commit this page was made from: the board is Tool/Documentation/HW/Rev A/LoadController.kicad_pcb and its schematic Tool/Documentation/HW/Rev A/Drivers.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LoadController design in my own project?
Its repository states no licence, so its author keeps all rights: ask DanielPopa1109 before reusing the design.
