Questions
How big is the Wv battery interface PCB?
It measures 60.5 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wv battery interface use?
36 parts, built around the ATTINY204-SSN, BZX84-C10 and MMBT5551L. 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 Wv battery interface KiCad files?
From the GravisZro/wv_battery_interface repository on GitHub, at the commit this page was made from: the board is wv_battery_interface.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wv battery interface design in my own project?
Its repository states no licence, so its author keeps all rights: ask GravisZro before reusing the design.
