That worries me... I would have said Logic level MOSFET.. Though 5v is best, as I understand logic level MOSFETS are even capable at 3.3v, with gate voltages as low as 2v in spec. A Logic MOSFET would seem the thing I would now go with.. Am I missing something?
I just purchased these, they're rated for 12A @ 60v.. Logic level, n channel mosfet. Got twenty of them from another vendor, seven bucks shipped.
The other approach is to use a supply that limits the current to less than the stall current, so that the controller doesn't have to carry such a high current.
Looks like ill go for the Logic Level MOSFETs. Am i right when i say that what defines a Logic Level MOSFET is the low gate threshold voltage (Max 5v) ?
