Questions

How big is the Supercap PCB?

It measures 72.3 × 70.9 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Supercap use?

79 parts, built around the TLV2372IP and ACS71240KEXBLT-010B3. 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 Supercap KiCad files?

From the ut-ras/rm_electrical-supercap_v2 repository on GitHub, at the commit this page was made from: the board is KiCAD/Supercap.kicad_pcb and its schematic KiCAD/Supercap.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Supercap design in my own project?

Its repository states no licence, so its author keeps all rights: ask ut-ras before reusing the design.
