<p>Product selling points: Widely used</p> <p>Small size, easy to carry</p> <p>Stable performance</p> <p>Easy to use</p> <p>Number of control channels: 8</p> <p>Functional characteristics</p> <p>1. Onboard STM32 is used to generate high-resolution PWM signals for precise control; </p> <p>2. Support manual mode and center return mode, switch through buttons, with mode indicator light; </p> <p>3. Support knob adjustment control in manual mode; </p> <p>4. Number of control channels: 8; </p> <p>5. Servo control accuracy: 0.09 degrees (. PWM minimum change value of 1us); </p> <p>6. Support servo with a control cycle of 20ms and a pulse width between 0.5 and 2.5ms</p> <p>7. Can directly use the 2S lithium battery charging head for debugging and returning to the steering gear; </p> <p>8. Power supply voltage range: 5-9V (specific based on the actual servo power supply voltage used); </p> <p>9. Each servo interface has a self recovery fuse to prevent excessive current from burning out the servo; </p> <p>Instructions for use: </p> <p>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.</p> <p>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.</p> <p>About wiring: </p> <p>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.</p> <p>Material: PCB</p> <p>colour: As Shown</p> <p>Package Contents: </p> <p>1 x 8-way servo controller debugging board</p> <p>Only the above package content, other products are not included.</p> <p>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.</p>
