Package Contents:
1*Motor controller board
Precautions:
1. The power circuit of the main board has no fuse, and the built-in self-addition cause the board chip to be permanently damaged (even if it is 2 seconds).
2. During normal operation, there is a sampling overcurrent protection at the motor output. Since the power and current of the module are very large, do not short circuit when the module does not work normally. Once the short circuit has the possibility of burning , the first wiring test machine uses low current and low voltage, after ok, high current and high voltage passes, because it is a bare board module for sale , pay attention to the wiring line insulation, strong voltage is not allowed to touch the board parts.
3. Do not connect the motor that is clearly inconsistent with the voltage and current of module or that is far from each other.
Only the above package content, other products are not included.
