Feature:1. Onboard STM32: The onboard STM32 is used to generate high resolution PWM signals, with precise control and plug and play.2. 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.3. 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.4. High Accuracy: The control accuracy of the steering gear controller is 0.09 degrees, the error is extremely small, and the response is sensitive.5. 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 ControllerMaterial: PCB.Package List:1 x Servo Controller8 x Knob CoverNote:Because the steering gear is a relatively powerconsuming device, the power supply current for the steering gear must be sufficient.
