Based on afew quick tests the bipolar motors are alot stronger than the unipolar motors I been using to test. The bipolars are slower but they have 200steps per rotation in fullstep mode and 400 in halfstep.
| A simple and cheap L298 based stepper motor controller. The phases are driven by 4 outputs from the PC parallel port/Mega8. |
| The mega8 controls the 2 phases of the stepper motor using 4 outputs. The mega8 receives commands for the PC over the serial port and converts them into pulses. |
