Which is better? PWMPAL/Motor Mind B/ Motor Mind C

I'm looking for something that will work in conjunction with A BS2P24, that will drive a Continuous DC motor (like those found on a model R/C boat). I haven't actually selected the motor yet, but I would like it to be fast.

I saw that I could directly control servos from the BS2P24, but I didn't know if maybe a motor control such as PWMPAL could also be used to control Servos (say 1-2) and a continuous DC motor.

    The PWMPAL does not inlcude an h-bridge, so the MotorMind would probably better for you.

    Yup, use the MotorMind to control the motor, then the BS2p24 to control the servo's. Servo's get 'refreshed' every 20 mSec, which means the BS2p can easily control a few of them. A DC motor requires an H-Bridge and something to provide the continuous PWM signal -- which the MotorMind should give you.

    Oh, and I believe the PWMPal is designed to control lots of Servo's -- it probably won't control a DC motor.
