Some basic info about USB in c/technology@lemmy.world
[–] tia@lemmy.world 84 points 1 week ago (1 children)

The PD standard document (freely available on usb.org) is over 800 pages long and features a lengthy part about the role of the cable alone which is mostly hidden from the user. Here's a short video about this issue: https://www.youtube.com/watch?v=6bZ0y9G-4Pc

I learn more about cables in this channel every week. Just wanted to share

USB-C cables can talk in c/technology@lemmy.world

It indeed is, but there seem to be no testers available for resistance measurements.

The USB-C cable tester in this video looks really good, but it seems to be unavailable for now: https://ble.caberqu.com

Are there any alternatives I can buy right now?
