Questions
How big is the SingleCharger PCB?
It measures 120 × 130 mm and has 4 copper layers, 1.6 mm thick.
What parts does the SingleCharger use?
95 parts, built around the TPS54360BDDAR, ADS1115IDGSR, LM358 and UCC27324DR-TP. 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 SingleCharger KiCad files?
From the BatteryMaximus/Dock-PCB repository on GitHub, at the commit this page was made from: the board is SingleCharger/SingleCharger.kicad_pcb and its schematic SingleCharger/Battery.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SingleCharger design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
