Questions

How big is the AUPWSW PCB?

It measures 100 × 50 mm and has 4 copper layers, 1.57 mm thick.

What parts does the AUPWSW use?

77 parts, built around the TSV991AILT, USBLC6-2SC6, LSR976 and BLM21BB050SN1. 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 AUPWSW KiCad files?

From the Michalek007/CurrentSensingCircuit repository on GitHub, at the commit this page was made from: the board is KiCad/AUPWSW.kicad_pcb and its schematic KiCad/AUPWSW.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the AUPWSW design in my own project?

Its repository states no licence, so its author keeps all rights: ask Michalek007 before reusing the design.
