Questions
How big is the SmallKatBatteryCharger PCB?
It measures 50 × 50 mm and has 4 copper layers, 1 mm thick.
What parts does the SmallKatBatteryCharger use?
58 parts, built around the BQ29200DRB, CSD87312Q3E, MIC5504-3.3YM5 and BUK7M33-60EX. 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 SmallKatBatteryCharger KiCad files?
From the SmallKatMQP/SmallKatBatteryCharger repository on GitHub, at the commit this page was made from: the board is SmallKat Battery Charger.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SmallKatBatteryCharger design in my own project?
Its repository states no licence, so its author keeps all rights: ask SmallKatMQP before reusing the design.
