Questions
How big is the CurrentSensorV1 PCB?
It measures 37.3 × 27.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CurrentSensorV1 use?
23 parts, built around the AMS1117-3.3. 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 CurrentSensorV1 KiCad files?
From the DerekParks/CurrentSensor repository on GitHub, at the commit this page was made from: the board is board/CurrentSensorV1/CurrentSensorV1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CurrentSensorV1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask DerekParks before reusing the design.
