Hello,
Probably a stupid question…
I have just received this USB A / USB C / Volt meter
https://www.stedi.com.au/rocker-switch-usb-c-usb-a-volt-meter.html
to replace this USB A / Volt Meter.

I assumed the wiring would just be the same and I’d basically unplug the positive and negative terminals on the old one and connect to the new one, job done. I should have looked a bit harder, anyway…
However the new one has 3 wires coming from it, red (I assume positive) black (I assume earth) and blue.
What is the blue wire for
? No wiring diagram came with it.
Edit: got it sorted
