Questions
How big is the Battery cap PCB?
It measures 59.8 × 73.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Battery cap use?
12 parts, built around the ARDUINO UNO R3 and IRFZ44NPBF. 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 Battery cap KiCad files?
From the lhr-solar/Power-BattCapacityTesterPCB repository on GitHub, at the commit this page was made from: the board is Battery-CapacityTesterPCB/battery cap.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Battery cap design in my own project?
Its repository states no licence, so its author keeps all rights: ask lhr-solar before reusing the design.
