Questions
How big is the Sensorstick PCB?
It measures 85 × 23 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sensorstick use?
8 parts, built around the HS91L02W2C01. 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 Sensorstick KiCad files?
From the MayNiklas/sensorstick repository on GitHub, at the commit this page was made from: the board is sensorstick/sensorstick.kicad_pcb and its schematic sensorstick/sensorstick.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sensorstick design in my own project?
Its repository states no licence, so its author keeps all rights: ask MayNiklas before reusing the design.
