Questions
How big is the Steering Sensor (1) PCB?
It measures 30 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Steering Sensor (1) use?
14 parts, built around the TLV2372IP and RDER71H104K0M1H03A. 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 Steering Sensor (1) KiCad files?
From the dnz1666/impedance-buffer-pcb repository on GitHub, at the commit this page was made from: the board is Steering_Sensor (1).kicad_pcb and its schematic Steering_Sensor (2).kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Steering Sensor (1) design in my own project?
Its repository states no licence, so its author keeps all rights: ask dnz1666 before reusing the design.
