Questions
How big is the BatteryAnalyzer MkII PCB?
It measures 101.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BatteryAnalyzer MkII use?
25 parts, built around the TLV2372IP, INA219AID and IRLZ44N. 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 BatteryAnalyzer MkII KiCad files?
From the Moragor/BatteryAnalyzer_MkII repository on GitHub, at the commit this page was made from: the board is KiCad files/Battery_analyzer_MKII/Battery_analyzer_MKII.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BatteryAnalyzer MkII design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
