For the full article check out my website! https://www.cranberrygrape.com/mini-projects/foot-pedal-enhanced/I purchased one of these pcsensor FS2020U1 USB Foot Switch Control devices from aliexpress a bit back (from a different seller that is no longer available for this model).Initially I was going to use the existing wires coming from the board but realized it powered the sensor by doing a round-robin power setup powering one signal pin at a time while checking the state of the others (using a reverse biased diode to power the board from the main board). The main board still surfaced the power pin though (each of the side boards is a duplicate of the main) so I realized I could replace the wire with a 5 wire one I grabbed from Amazon and be able to use this with my projects going forward.The existing piece this is replacing is an injection molded plastic piece with strain relief built in. I opted to use holes for a zip tie for my own strain relief here.It works rather well and with this setup I'm able to use a SAMD21 to send mouse or keyboard commands on touch, can make lots of interest projects utilizing it as an actuator, and so on.
