It includes built-in over-current protection to help prevent damage to the chip and connected motor.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I identify the COM terminal on a 4-wire brushless motor?\u003c\/h4\u003e\n\u003cp\u003eA: Use a multimeter set to resistance mode. Test each of the four terminals against the other three. The terminal that reads the lowest — and equal — resistance to all three remaining terminals is the COM (common) terminal. Correctly identifying this terminal before connecting to the driver board is important for proper operation.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I control the motor speed with this driver board?\u003c\/h4\u003e\n\u003cp\u003eA: Yes.
