Product selling points: Widely used Small size, easy to carry Stable performance Easy to use Number of control channels: 8 Functional characteristics: 1. Onboard STM32 is used to generate high-resolution PWM signals for precise control; 2. Supports manual mode and center return mode, switchable via buttons, with mode indicator light; 3. Supports knob adjustment control in manual mode; 4. Number of control channels: 8; 5. Servo control accuracy: 0.09 degrees (PWM minimum change value of 1us); 6. Supports servo with a control cycle of 20ms and a pulse width between 0.5 and 2.5ms; 7. Can directly use the 2S lithium battery charging head for debugging and returning to the steering gear; 8. Power supply voltage range: 5-9V (varies based on actual servo power supply voltage); 9. Each servo interface has a self-recovery fuse to prevent excessive current from damaging the servo. Instructions for use: The steering gear is a power-consuming device that draws significant current, so the power supply must provide sufficient current. If the power indicator light flashes, the steering gear rotates uncontrollably, or positioning errors occur, this indicates insufficient power supply and the power source should be replaced. Wiring instructions: Connect VCC and GND to the power supply and plug the servo into the 2x3P pin header. VCC is positive, GND is negative, and S is the signal terminal.
