Questions
How big is the Haptic feedback PCB?
It measures 30 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Haptic feedback use?
30 parts, built around the DW01A, TP4056-42-ESOP8 and AO3400A. 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 Haptic feedback KiCad files?
From the devaexe00/Projects repository on GitHub, at the commit this page was made from: the board is haptic feedback/haptic_feedback/haptic_feedback.kicad_pcb and its schematic 8channel relay module/relaymodule.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Haptic feedback design in my own project?
Its repository states no licence, so its author keeps all rights: ask devaexe00 before reusing the design.
