Questions
How big is the ANC PCB?
It measures 46.1 × 58.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ANC use?
85 parts, built around the TLV172IDCK, CMM-3729AB-38308-TR, ICS-40730 and LD39015M12R. 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 ANC KiCad files?
From the Poojaa-Rangaiah/Kicad_Projects repository on GitHub, at the commit this page was made from: the board is ANC/ANC.kicad_pcb and its schematic 4LayerMCUdatalogger/Connectors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ANC design in my own project?
Its repository states no licence, so its author keeps all rights: ask Poojaa-Rangaiah before reusing the design.
