Questions
How big is the QI Charger PCB?
It measures 150 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the QI Charger use?
322 parts, built around the 74LVC1G06Z, 74LVC1G17Z, 74LVC1G07 and OPA340NA. 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 QI Charger KiCad files?
From the drewsum/QI_Charger repository on GitHub, at the commit this page was made from: the board is hdw/QI_Charger/QI_Charger.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the QI Charger design in my own project?
Its repository states no licence, so its author keeps all rights: ask drewsum before reusing the design.
