Hi,
I would like to know whether SD02B stepper motor driver can drive 5V stepper motor or not? However, i found out that in the user manual stated that it is able to drive stepper motor from 3V-40V. I have tried to connect 5V stepper motor with 5V input supply to SD02B at Vmotor pin and GND pin but the motor didn't move when i pressed the "test" switch (for few second). Any suggestion that I can solve this problem
