Swiss Pi Extensions – Servo Motor Extension
With the servo motor extension board (Figure 7) you can connect more servo motors to the Swiss Pi than the four supported directly. With two of these boards you can control a maximum of sixteen servo motors.
The resistors protect the Swiss Pi in the event that the threepin plug of a servo motor is accidentally connected the wrong way.
In combination with the previous article and the many software examples described there , you now have an arsenal of tools to tackle a wide range of applications with the Swiss Pi / Raspberry Pi duo.
