• It is a Eight-way servo controller, debug board, robotic arm test board, driver knob, 8-way PWM development, industrial control.
• Since the servo is a power-consuming device, the current supplied to the power source needs to be sufficient. When the servo is rotating, the on-board LED flashes, the servo rotates uncontrollably, or the error is obviously too large, indicating that the current of the power supply is insufficient and the power supply needs to be replaced.
• The positive voltage of the steering gear power supply is 5V~8.4V, and the specific voltage of the steering gear supply is based on the actual power supply voltage.
• 5~8.4V wide voltage input,Anti-reverse protection & Overcurrent protection.
