Now, it is time to connect the servo cables to the cyber:bot board. Then, you will set the servo ports' power jumper, based on what kind of batteries you are using. But first:
There is a smaller 3- pin header to the left of the servo ports. A shunt jumper connects two pins on it, selecting the voltage source supplied to the servos. The 5V setting limits the voltage to 5V, regardless of the input voltage. The VIN setting supplies the servo with whatever voltage level is connected to the board.
The Continuous Rotation Servos need 4 to 6 VDC to operate. So, the setting you should use depends on the kind of batteries you have.
Now you are ready to go to the next tutorial: Navigation with the cyber:bot. [1]
