Questions
How big is the Pdcharger 100W PCB?
It measures 91.5 × 48.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pdcharger 100W use?
97 parts, built around the SN65HVD230D, 24LC512-I/P, SL1B and PA5433.103NLT. 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 Pdcharger 100W KiCad files?
From the NerdyProjects/PDbatCharger repository on GitHub, at the commit this page was made from: the board is hw/pdcharger_100W.kicad_pcb and its schematic hw/pdcharger_100W.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pdcharger 100W design in my own project?
Its repository states no licence, so its author keeps all rights: ask NerdyProjects before reusing the design.
