USB was supposed to rule them all but it’s now a mess of standards sharing the same connector. Different speeds, voltage, charging protocols, alt modes, even the number of pins used is variable… For those asking, the thing is available on Kickstarter
but where is the diy version that we actually want that uses arduino or esp or something with all the details on a git readme?
