Questions
What parts does the UPS use?
33 parts, built around the NE555, BC548 and IRF540N. 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 UPS KiCad files?
From the IoTCloudStudio/HW_Develop repository on GitHub, at the commit this page was made from: the board is Productivo/Cloud UPS/PCB/UPS.kicad_pcb and its schematic Productivo/Cloud UPS/V2/UPSV2concepttocheck.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UPS design in my own project?
Its repository states no licence, so its author keeps all rights: ask IoTCloudStudio before reusing the design.
