1.Introduction:
It is a single-channel servo controller debug board, robotic arm test board, driver, simple knob, synchronous PWM development.

2.Feature:
1>.Use high-precision pots to achieve simultaneous control of potentiometers.
2>.The onboard 8-bit MCU can generate high-resolution PWM signals and control accurately.
3>.Support three control modes.
4>.Anti-reverse polarity protection & over-current protection
5>.Micro USB (5V) and terminal (6-8.4V) dual power supply ports.
6>.The dual servo can be adjusted at the same time through a single knob.

3.Parameter:
1>.Terminal power supply: suitable for conventional 6~8.4V high-voltage servos.
2>.Micro USB power supply: suitable for conventional 5V standard voltage servos.
3>.Steering gear control accuracy: 0.09 degrees (i.e. P M limit small change value 1us).
4>.Support control period: 20ms Pulse width: O.5ms-2.5ms.
5>.Work Temperature:-25℃~85℃
6>.Work Humidity:0%~95%RH
7>.Size: 49.5*35MM

4.Methods of Use:
1>. The servo is plugged into the 3Pin servo port. + is the positive pole, - is the negative pole , s is the signal terminal ;
2>. Default potentiometer control mode (red LED on) when the power is turned on, and the steering gear rotates in the same step when the knob is turned;
3>.The buttons under the knob can switch between three control modes, which are:
     Centering mode: One button to center turns the servo to 90° and returns to the center position, the red LED is off, and the blue LED is on.
     Reciprocating mode: The steering gear will reciprocate from 0°~180° in reciprocating mode, and the red and blue LEDs will flash alternately.
     Manual mode: The manual control knob can be used to rotate the steering gear angle at the same time, the blue LED is off, and the red LED is on.

5.Note:
1>.Since the servo is a power-consuming device, the current supplied to the power source needs to be sufficient. When the rudder is rotating, when the onboard power indicator light flashes, the steering gear rotates uncontrollably, or the error is obviously large, it means that the current of the power supply is insufficient and the power source 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.
3>.Micro USB input 5V voltage, terminal socket input 6~8.4V voltage, the two sockets can not be used at the same time.

6.Package:
  1pcs Single-channel servo controller.
