8CH Rotary Knob Servo Driver 8 Channel/Way Controller Board Overcurrent Protection Servo Tester Servo Controller Durable _x000D_ _x000D_ _x000D_ 8CH Rotary Knob Servo Driver 8 Channel/Way Controller Board Overcurrent Protection Servo Tester Servo Controller, Durable _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ Product selling points: Widely used _x000D_ Small size, easy to carry _x000D_ Stable performance _x000D_ Easy to use _x000D_ Number of control channels: 8 _x000D_ _x000D_ Functional characteristics _x000D_ 1. Onboard STM32 is used to generate high-resolution PWM signals for precise control; _x000D_ 2. Support manual mode and center return mode, switch through buttons, with mode indicator light; _x000D_ 3. Support knob adjustment control in manual mode; _x000D_ 4. Number of control channels: 8; _x000D_ 5. Servo control accuracy: 0.09 degrees (i.e. PWM minimum change value of 1us); _x000D_ 6. Support servo with a control cycle of 20ms and a pulse width between 0.5 and 2.5ms _x000D_ 7. Can directly use the 2S lithium battery charging head for debugging and returning to the steering gear; _x000D_ 8. Power supply voltage range: 5-9V (specific based on the actual servo power supply voltage used); _x000D_ 9. Each servo interface has a self recovery fuse to prevent excessive current from burning out the servo; _x000D_ Instructions for use: _x000D_ The steering gear is a power consuming device that consumes a lot of electricity, so the current of the power supply needs to be sufficient. _x000D_ If the power indicator light flashes, the steering gear rotates uncontrollably, or the error is obvious, it indicates that the power supply is insufficient and needs to be replaced. _x000D_ About wiring: _x000D_ Connect VCC and GND to the power supply and plug the servo into the 2X3P pin. VCC is the positive pole, GND is the negative pole, and S is the signal terminal. _x000D_ Material: PCB _x000D_ colour: As Shown _x000D_ _x000D_ Package Contents: _x000D_ 1 x 8-way servo controller debugging board _x000D_ _x000D_ Only the above package content, other products are not included. _x000D_ Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_
