Questions
How big is the BatteryPod PCB?
It measures 71.5 × 86.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BatteryPod use?
41 parts, built around the CAT24C256LI, TPS25750DRJKR and CDEP15D90T150NP-220MC-125. 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 BatteryPod KiCad files?
From the cryptoAlgorithm/BatteryPod repository on GitHub, at the commit this page was made from: the board is BatteryPod.kicad_pcb and its schematic BatteryPod.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BatteryPod design in my own project?
Its repository states no licence, so its author keeps all rights: ask cryptoAlgorithm before reusing the design.
