| Problem | Likely Fix | |------------------------|---------------------------------------------| | Motor not moving | Check common ground, VM power, logic levels | | One motor weak | Swap motors to test; check PWM frequency (<20 kHz) | | Module gets very hot | Reduce load current or voltage; check for stalled motor | | Erratic direction | Verify IN1/IN2 are not both floating or both high |

If your HW-417-v1.2 driver is installed but you still cannot communicate with your microcontroller, check the following: Likely Cause Faulty USB cable or driver not loaded.
