Questions
How big is the Sensor board PCB?
It measures 40.6 × 30.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sensor board use?
37 parts, built around the BC805M, TPL5111EVM, TPS22917DBV and CR0603FA3303G. 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 board KiCad files?
From the aahmad-p/iot_tap_sensing repository on GitHub, at the commit this page was made from: the board is ECAD/sensor_board/sensor_board.kicad_pcb and its schematic ECAD/sensor_board/sensor_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sensor board design in my own project?
Its repository states no licence, so its author keeps all rights: ask aahmad-p before reusing the design.
