Why doesn't standard USB-C use both of the pairs. USB-C is not a protocol. USB Type C is the name of a connector and cabling specification; it's not the name of the protocols that are used over those connectors and cables. When doing USB protocols over Type C cables, you're doing USB 3.1 Gen 2 (10Gbps "SuperSpeed+"), or earlier flavors of USB.
USB-C is an industry-standard connector for transmitting both data and power on a single cable. The USB-C connector was Until recently, many USB-C ports carried the USB 3.1 label ("USB 3.2 With this cable, you have VBUS, GND and CC. The charger itself has the USB CC pullup resistor and monitors the CC voltage for other power profiles. Your plan is converting this to an USB C plug to micro USB plug (data & power left to right). You would need to remove the CC wire from the PCB and wire it up via an 5.1K resistor to ground.This simplicity means USB-C cables are highly interchangeable, so users can store fewer cables. Of course, laptop and desktop ports can also be simplified. USB-C’s reversibility entails bi-directional charging, meaning that, in principle, at least, it’s possible to charge any device from any other.
Step 1: Items You Will Need. Straight forward, these are the items you will need to make a custom length USB cable: A piece of Cat-5 cable, length you desire. Extra USB connectors that come with a 6-in-1 type cable (if you ever had to purchase one like me, you probably have at least a couple you have absolutely no use for) Razor knife (careful
