Questions
How big is the Car battery logger PCB?
It measures 49.9 × 49.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Car battery logger use?
50 parts, built around the ATMEGA328P-AU and L4931CD33-TR. 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 Car battery logger KiCad files?
From the sbaconbits/car_battery_logger repository on GitHub, at the commit this page was made from: the board is kicad/car_battery_logger/car_battery_logger.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Car battery logger 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).
