    I am wiring up the firing boards and solenoids for my Bismarck. On the B turret, I would like to have twin side mounts.

    I am trying to be cheap. Can I have a single pololu board trigger two solenoids. The math checks out that they board can easily handle two solenoids. Does anyone see anything inherently wrong with his plan?

    solenoid: 6.5W
    system: 11.1V

    6.5W / 1.1V = .5856 * 2 = 1.1712 amp draw. The board is rated to 15amps.

    You definitely can. I use one of those boards to fire my rewound, ridiculously too large solenoids in my Bart. If it can handle them it'll handle whatever you throw at it.
