Features Knob Control: The steering gear controller has 8 way knob adjustment, and directly turning the potentiometer can control the steering gear to rotate within the range of 0 to 180 degrees. Switchable Mode: The servo controller supports manual mode and return mode, which can be switched by buttons, which is very convenient to use and operate. High Accuracy: The control accuracy of the steering gear controller is 0.09 degrees, the error is extremely small, and the response is sensitive. Onboard STM32: The onboard STM32 is used to generate high resolution PWM signals, with precise control and plug and play. LED Indicator: The servo controller has a mode indicator. When the LED flashes, it means that the power supply current is not enough, and the power supply needs to be replaced. Specification: Item Type: Servo Controller Material: PCB Package List:1 x Servo Controller 8 x Knob Cover Note:Because the steering gear is a relatively power‑consuming device, the power supply current for the steering gear must be sufficient.
