I'm new to electronics so please bear with me.
I'm stripping a USB cable that I want to connect to another component - a 5V fan for example.
On the side pictured, i'm connecting up to a 5V fan. And on the other side is a regular USB connector which will plug in to a 5V DC power supply.
After stripping, I have noticed there is a outer wire running along the cable. On the left of the picture:
From my searching i've found this is a shielding wire. Is this correct? In the case where i'm not looking to shield and only provide power supply (not even use the data wires) what should I do with this extra wiring of the shield? I have heard that shield should be grounded. So should I:
- Combine shield and ground wire
- Ground shield wire separately
- Leave shield wire floating
