Physical Goods:

Program features: 

1. Rated operating voltage range: 2.5~18V 

2. Maximum operating current: 2A 

3. Maximum subdivision: 128 

4. No current detection resistance. 

5. Ultra-low standby current of 0.1mA.

 6. Support forward, invert and standby functions.

 7. Run the motor smoothly and noiselessly and reduce vibration. 

8. The small size of the component saves the wiring space of the printed circuit board (PCB), which helps to reduce costs.

9. It can be used with the 1.8V interface to connect various hosts and microcontrollers. 

10. Improve the accuracy of the rotation angle through micro-step control.

 11. The interior contains overcurrent detection protection and overtemperature protection to prevent potential safety hazards and make it safer to use.
