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. Support manual mode and center return mode, switch through buttons, with mode indicator light 3. Support 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. Support 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 (specific based on the actual servo power supply voltage used) 9. Each servo interface has a self recovery fuse to prevent excessive current from burning out the servo Instructions for use: 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. 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. About wiring: 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.
