I am going in circles on the web and appreciate your help with this novice question, operate a solenoid with a mosfet (original idea, I know). I bought a Gravity DFR0457 to switch a 12V solenoid on from a camera remote (Pocketwizard) that outputs 3v3. I can't get it to work (apparently common with logic level needing more voltage), so i am guessing i have to bump up the output remote 3v3 somehow?. Is this even the correct route to go? I was hoping that I could use existing boards so i wouldn't have to solder together different components.

You're going to have to supply 12V separately. An all-in one relay/solenoid driver with a MOSFET, gate resistor, and coil diode in the same package could be soldered to a little breakout board fairly easily. The NUD3112 could be an attractive option.
