Precautions: 1. There is no fuse in the power supply circuit on the motherboard. has added it himself. Reverse connection of the positive and negative poles of the power supply cause permanent damage to some of the chips on the board (even if it does not work for 1 second) 2. There is motor blocking protection during normal operation. Please do not artificially short-circuit when the module is not working normally. Once short-circuiting may cause to burst, please use small current and low voltage test for the first wiring test. Matching use of three-phase DC brushless motors with equivalent current and power 3. Do not connect the motor that is obviously inconsistent with module voltage, current, or power, to avoid inexplicable "nonsensical" damage
