    PWM/MOSFET output module

    Hey boys and girls...

    I'm designing the PWM/MOSFET output board. The specs so far:

    2-channel
    40A/channel
    40 volts
    Works with any V4 board

    $20 per board.

    Any changes before I send it out for production?

    Sorry, civicmods

    No need to be sorry, there is nothing wrong with a bit of competition.

    PWM when?

    How are you making out on the PWM board? What uses are you designing for?

    Would this allow me to drive the servos from Lego MindStorm? Just a servo and it's got a optical tach built into the gear housing. I'll bet that can go straight to the Brain, now. My brain wants its own limb, in the greenhouse that it watches over.

    Probably not. This lets you drive a regular DC motor. Most servos need to be commanded every 1.5mS. The brain can't output that fast.... yet.
