8 Wire Stepper Motor Wiring Diagram. Wiring diagram for nema17 is given below. L298n motor driver with stepper motor and arduino wiring diagram.
Means it covers 18 degrees in every step. Finally since i designed the circuit to drive a unipolar stepper motor connect the 5th wire red in the case of this stepper motor to the com pin. Nema 17 stepper motor technical specifications.
Original size my power supply is a lab bench power supply set to 12v i use esp 32 cam for two reasons.
Then using the pinout diagram for the uln2803a connect the gnd pin pin 9 to the negative rail and connect the com pin pin 10 to the positive rail. This breakout board for tis drv8825 microstepping bipolar stepper motor driver features adjustable current limiting over current and over temperature protection and six microstep resolutions down to 132 step. I followed your guide to drive a nema 17 stepper motor bipolar 18 deg 26ncm 368ozin 04a 12v 42x42x34mm 4 wires 17hs13 0404s through the arduino motor shield rev 3 board by powering it separately. The circuit diagram for the arduino stepper motor control project is shown above.
