[Physically Verified] Data Cable Continuity Tester

Overview

I've been organizing my data cables lately—Micro, Type-C, and dual-C—there are so many!
It's a dense, overwhelming pile. Some cables only provide power, not data transfer, and some dual-C cables lack a CC (compass) for voltage identification.
I can't possibly test every single cable,
so I made this little gadget. You plug the IN cable in on the left and the OUT cable on the right to identify the cable.
It's simple, but quite practical!

The one above only has two wires. Regular power cables

have D+ and D- data transfer capabilities, while

this one has a CC. But usually, people are lazy and only make one CC1 or CC2 to reduce costs.

It's truly a thoughtful design to include both CCs!
