Questions
How big is the Current Sensor PCB?
It measures 68.5 × 34.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Current Sensor use?
36 parts, built around the NXE1S0505MC-R7, TLV9001IDCK, AMC1300DWV and LM2776DBV. 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 Current Sensor KiCad files?
From the ExcessiveMotion/drive-hardware repository on GitHub, at the commit this page was made from: the board is KiCad/Current Sensor/Current Sensor.kicad_pcb and its schematic KiCad/Current Sensor/Current Sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Current Sensor design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
