What is the pink wire in a USB cable?
The pink white should be the V+ and Data +. The grey/white should be the V- and Data -. But really… the data wires should be twisted together for noise immunity. Except that most USB’s should have an outer layer of conductive material (coaxial cable can have a drain wire and aluminum cover.)
What are the 4 pins in USB?
USB Connector Pinouts
| Pin | Name | Cable color |
|---|---|---|
| 1 | VCC | Red |
| 2 | D- | White |
| 3 | D+ | Green |
| 4 | GND | Black |
Can you cut and join USB cables?
USB cables can be cut and spliced together to create a longer or even a shorter cable depending on your needs. Splicing two USB cables can create a special-purpose cable that can save you from having to find and purchase one.
What do the colors on USB ports mean?
