You can build a stepper motor controller on a separate circuit board, then
remove the motor control IC's off the handy board
and use the output signals to control your stepper. Will have to write a
program to run it. you will need a min of 4 outputs to drive
2 steppers 2) for Direction and 2) for steping. That's if you use a stepper
controller IC. You can power your steppers of a separate power supply. The
handy board uses 8 output lines to control it's DC motors.
You can use a UCN5804 stepper conrtoller IC or build your own.

I hope that helps.

| Hi For a relatively simple solution you may want to look at (URL) have connected and run steppers using this method. It does not get the best from the motors but it will let you experiment easily. (27 years ago, 24-Apr-98, to lugnet.robotics.handyboard)
