Questions
How big is the Sensor PCB?
It measures 70 × 70 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Sensor use?
161 parts, built around the TCAN334GDCN, AD4111BCPZ, AP63203WU and OPA333AID. 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 Sensor KiCad files?
From the aesirkth/Sigurd repository on GitHub, at the commit this page was made from: the board is Hardware/Sensor.kicad_pcb and its schematic Hardware/ADC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask aesirkth before reusing the design.
