Ever wonder if your USB C cable is USB2 or USB3? Do you have some charge-only cables hiding in a box just waiting for the right moment to spoil your project plans?!
Fear no more!

I’ve made a simple board to test most of the things!

@alvaro i feel like this says everything that needs to be said about USB standards
@alvaro @skimbrel yeah, next project: Dear box, which USB charging protocol do you support? #usb #standards

@saper @alvaro “yes”

or “this one i made up myself, isn’t it great?”
