5V to 12V STEP UP INVERTER

[Mado]

Hi. I'd like to ask about the pinout of this 5V to 12V STEP UP INVERTER from the store (I ordered). Apart from ground it has two pins: V0 and V1. But which one is 12V output and which is 5V input? I could not find any pinout description and there seems to be no article in this forum up to now.

I plan to serve my 260 ST with just 5V and add the 12V with this little inverter.

(This is my first article here, hope it is correct to as this question here.)

Thanks a lot. The Vi on my board looks pretty much like V1. "i" and "o" makes sense.
