  • Yes it works. Just set the PWM pins to output and HIGH. For example the stepper_oneRevolution example works with this setup: Stepper myStepper(stepsPerRevolution, 7,8,4,9); void setup() { myStepper.setSpeed(300); pinMode(5, OUTPUT); pinMode(6, OUTPUT); digitalWrite(5, HIGH); digitalWrite(6, HIGH); }

    But since there is no hardware current limiting, steppers get hot real fast. And since the drivers do not work at low voltages such as 3V that are suitable for a lot of steppers, that can be a problem. Solution: get 12V steppers. Better solution: get a stepper driver with current limiting.

  • Hi, good to see you changed the 40V to 16V in the description.

    I tried mounting 5mm screw terminals, and they overlap the H-bridge ICs. Please update the design for the next batch.

  • So I can't use it with a 36V 12A motor ?
    If so please update the product description with real-world data, not absolute-maximum-ratings. Please confirm that, I may return the product.

No public wish lists :(
