I have a Revolution Mini (F4). There is no Rev printed on the case, but it has a black and white arrow pointing forward. Using LibrePilot 15.09 or 16.09 everything goes fine in the setup wizard until I get to motor #4. It does not activate. Swapping the PWM lead with motor #3, motor #4 does work, but #3 does not. The PWM lead from #5 does not activate a motor either, so it appears that only PWM leads 1-3 work. I have updated the firmware from both 15.09 and 16.09. I never tried the original firmware that came installed.
Does this sound like a bad module, in which case I would return it to HobbyKing, or could it be a firmware or setup issue? This is my first quad build so I am just learning about flight controllers. However I have 40 years experience building RC airplanes, and am a retired electronics/software technician.
Thanks for your suggestions.
P.S. The module has the OP logo on it.

Can you post a screenshot of your output configuration tab? It's possible you have something configured incorrectly.

Hi,
This board has nothing related to original OpenPilot project or a CC3D board, even if there is a OP logo on it.
That a Revolution board with Oplink modem externalized with an additional board, done by Chinese cloners.
I doubt there is a firmware issue, more likely a hardware issue.
You can check the board using original schematic:

Some components are removed but outputs should be the same.
