Description:

1. Maximum current of 2.5A

2. Six different step resolutions: full step , half step , 1/4-step1/8-step1/16-step, 1/32-step

3. CAN interface directly with 3.3 V and 5 V systems

4. Over-temperature thermal shutdown , overcurrent shutdown , undervoltage lockout

5. Short- to-ground short circuit load protection

6. 4 layer 2 oz copper PCB, in order to improve heat dissipation

7. Welding the ground below the bottom exposed to the driver IC on the printed circuit board pad

8. Module size , pin and interface matching A4988 stepper motor driver operators in many ways

9. Adjustable current control lets you set a potentiometer , which lets you use the rated voltage or more 10. stepper motors to achieve a higher rate of maximum output current step

11. Intelligent chopping control automatically selects the correct current decay mode ( fast decay or slow decay )

12. Maximum 45 V supply voltage

13. The built-in voltage regulator ( the need for any external logic supply voltage )
