Questions
How big is the FSR PAD PCB?
It measures 195 × 150 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FSR PAD use?
160 parts, built around the LM358, MCP3208-BI/P, 74HCT4051D and MMSD4148. 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 FSR PAD KiCad files?
From the leecurrent04/INHA_FSR_sensor repository on GitHub, at the commit this page was made from: the board is hw/FSR_PAD/FSR_PAD.kicad_pcb and its schematic hw/FSR_PAD/FSR_PAD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FSR PAD design in my own project?
Its repository states no licence, so its author keeps all rights: ask leecurrent04 before reusing the design.
