Description

The RC servo motor is very popular in RC (Radio Control), and now it is widely used in robotics. Yet, as many of you may already know, standard RC Servo cannot rotate continuously, there is a limit of around 270º or 180º. Unlike a simple motor, which spins either forward or backward, a servo provides rather gradual and precise movement, either left or right. They’re the steering mechanism in any remote-controlled car you’ve ever played with.

But to make it work, power alone is not enough. You need a control signal as well, or it will not move. With this server controller, you can use its knob to adjust the position manually or use the servo to return to the middle position, showing the voltage of the power supply.

Features:

  • Voltage range: 5~8.4VDC
  • 2 Working modes:
    • Neutral Position
    • Manual
  • 2 Types of power supply:
    • Connect the positive and negative terminal of lithium battery
    • Connect the charging port by using a lithium battery
  • Dimension (W*L): 35*50mm
  • Weight: 13.8g

Wiring method:

  • You can directly plug the charging end of the 7.4V lithium battery into the white terminal
  • Or connect the power supply to the blue terminal, and the positive voltage is 5~8.4V

How to use:

  • Connect power to the board
  • Plug the steering gear into the steering gear interface. + is the positive pole, -is the negative pole, and S is the signal terminal
  • Turn the knob, and the servo will rotate synchronously
  • There is a flexible button under the knob to switch modes:
    • Return to center: return to the middle position
    • Manual: knob control

Packing list:

  • 1 x Servo controller
Warranty Period: 12 months
