Application notes:

1. Confirm that the voltage and power parameters of the motor do not exceed the range of the driver board as specified.
2. The JYQD-V6.3E2 driver board is a bare board without housing and a heatsink. If the power of the motor is below 60W, it does not need to add a heatsink, It only needs to ensure normal ventilation and wall insulation. If the power of the motor is more than 100W, it must add a heatsink.
3. Please take note that the JYQD-V6.3E2 driver board has no anti-reverse connection protection, it will permanently damage the driver board if reversed polarity connection.
4. The 5V output port on the driver board prohibits connecting an external device. It is only applicable to the external potentiometer and switch of the board for speed regulation and reversal.
5. The “Signal” terminal on the JYQD-V6.3E2 driver board is the motor speed pulse output signal (push-pull output), and the maximum output current is less than 5mA.
