Any electronics wizards here?

Recommended Posts

I have an action cam which can be powered by an external battery using USB but I also have a mic that uses the same USB socket.

I'd like to make a connector that allows both at the same time.
I have the ability to make this connector but not sure if connecting the pins might damage the camera.

The battery will use pins 1 and 5 for power.
But the mic uses pins 1 and 2 so would that damage -data line 2?
I assume I'd need a diode on the mic positive to prevent current leaking through it?

I think the mic measures 948 Ohm resistance.

Thanks for any help
