Questions
How big is the SeneCurrent PCB?
It measures 93.8 × 89.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SeneCurrent use?
30 parts, built around the LMV358, TLC2652ACP, BZX84C3V3 and TP4056. 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 SeneCurrent KiCad files?
From the tadzio8425/SeneCurrent repository on GitHub, at the commit this page was made from: the board is SeneCurrent.kicad_pcb and its schematic SeneCurrent.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SeneCurrent design in my own project?
Its repository states no licence, so its author keeps all rights: ask tadzio8425 before reusing the design.
