1.Introduction:
It is a Eight-way servo controller, debug board, robotic arm test board, driver knob, 8-way PWM development, industrial control.

2.Feature:
1>.Use high-precision potentiometers, no programming required.
2>.The 8CH potentiometer and the servo should be controlled at the same time.
3>.Onboard 8-bit MCU, generating high-resolution PWM signals for accurate control.
4>.Support manual mode and centering mode.
5>.The terminal (5V-8.4V) power supply port has overcurrent protection function.
6>.5~8.4V wide voltage input.
7>.Anti-reverse protection & Overcurrent protection

3.Parameter:
1>.Steering gear control accuracy: 0.09 degrees (i.e. PWM limit small change value 1us)
2>.Support control period: 20ms, pulse width: 0.5ms-2.5ms
3>.Lithium battery power supply: suitable for conventional 6~8.4V high-voltage servos
4>.Lithium battery + power module power supply: suitable for conventional 5V standard voltage servos.
5>.Work Temperature:-25℃~85℃
6>.Work Humidity:0%~95%RH
7>.Size: 100*58MM

4.Using Method:
1>.Power supply to the control board, the voltage is 5V~8.4V, and the specific voltage is based on the actual amount of the steering gear;
2>.After powering on, the LED of the MCU position lights up and flashes twice in 5 seconds (blue LED);
3>.The servo is plugged into the 3Pin servo port. + is the positive pole , - is the negative pole , S is the signal terminal;
4>.Turn the knob and the servo will rotate at the same time;
5>.The button under the knob can switch the mode, and the following buttons are:
      Neutralization mode: One button turns the steering gear shaft to a 90° state.
      Manual mode: The manual control knob allows the steering gear angle to rotate at the same pace.

5.Note:
1>.Since the servo is a power-consuming device, the current supplied to the power source needs to be sufficient. When the servo is rotating, the on-board LED flashes, the servo rotates uncontrollably, or the error is obviously too large, indicating that the current of the power supply is insufficient and the power supply needs to be replaced.
2>.The positive voltage of the steering gear power supply is 5V~8.4V, and the specific voltage of the steering gear supply is based on the actual power supply voltage;

6.Package:
  1pcs 8-Channel servo controller.
