Álvaro PrietoEver 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!
Connect your cable to both sides and the signal LEDs will light up if they are connected. Here’s an example of a USB2 cable and a thunderbolt 3 cable.
Want to test a USBA to C cable? How about a USBA to MicroB? USBC to B? MiniB? You’ve got it!
Here’s what a the dreaded charge-only cables look like. I had to make my own since I had previously banished them from my lab!
Best part of all? It’s open hardware! If you want to make your own, here’s the kicad project: https://github.com/alvarop/usb_c_cable_tester
I made a few, so if you know me and want one, let me know :)
Shae Erisson@alvaro I would buy several of these, do you sell them online?
@shapr I don't, but you can get some made by JLCPCB. Here are the instructions https://github.com/alvarop/usb_c_cable_tester/blob/main/ORDERING.md
