I'm looking for a driver for a bipolar stepper that can be driven by the propeller capable of supplying 5-10amps to a fairly sized bipolar stepper motor. Does anyone know where I can get one for a reasonable amount of money?
I've seen those drivers at other sites and if I remember correctly they need TTL level on the inputs.
I've gotten a couple of drivers already for smaller motors from pololu and probotix that work with the propeller directly but are limited to 2 - 2.5 amps. I need "more power". :-)

I reckon they're OK with 0/3V control signals from the Propeller. Most everything 0/5V is "happy" with a >= 3V HI.
In any event, there are ways and means to overcome.

Anyway, in case you didn't plug around at ebay
