Questions
How big is the DemoCurrentSensor PCB?
It measures 50 × 28 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DemoCurrentSensor use?
16 parts, built around the ESP32-WROOM-32 and TPS613221ADBV. 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 DemoCurrentSensor KiCad files?
From the Coopdis/demoCurrentSensor repository on GitHub, at the commit this page was made from: the board is pcb/demoCurrentSensor.kicad_pcb and its schematic pcb/demoCurrentSensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DemoCurrentSensor design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
