Questions
How big is the LifeCounter PCB?
It measures 100 × 74.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LifeCounter use?
210 parts, built around the TPS630701RNMR, 74HC595, 74LVC3G14DC and BQ24090DGQR. 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 LifeCounter KiCad files?
From the Dinamiet/LifeCounterPCB repository on GitHub, at the commit this page was made from: the board is LifeCounter.kicad_pcb and its schematic LifeCounter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LifeCounter design in my own project?
Its repository states no licence, so its author keeps all rights: ask Dinamiet before reusing the design.
