Questions
How big is the E whammy hal sensor PCB?
It measures 17 × 26 mm and has 2 copper layers, 1.66 mm thick.
What parts does the E whammy hal sensor use?
16 parts. 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 E whammy hal sensor KiCad files?
From the cycfi/e_whammy repository on GitHub, at the commit this page was made from: the board is e_whammy_hal_sensor.kicad_pcb and its schematic e_whammy_hal_sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the E whammy hal sensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask cycfi before reusing the design.
