Questions
How big is the USB Charger PCB?
It measures 36.4 × 56.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the USB Charger use?
19 parts, built around the LTC3872ITS8#TRMPBF and SI3456DDV. 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 USB Charger KiCad files?
From the porwal97/CTS repository on GitHub, at the commit this page was made from: the board is PCB design /USB_Charger/USB_Charger.kicad_pcb and its schematic PCB design /CTS Device - Copy/CTS Device.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the USB Charger design in my own project?
Its repository states no licence, so its author keeps all rights: ask porwal97 before reusing the design.
