Overview

The Digilent PmodCON3 (Revision C) can be used to easily interface with up to four small servo motors that deliver

anywhere from 50 to 300 ounce/inches of torque, such as those used in radio controlled airplanes or cars, as well

as some mechatronics projects.

1 Functional Description

The PmodCON3 allows any Digilent system board to easily interface with a standard 3-wire servo motor consisting

of a signal, positive power supply, and ground power supply wires. The power supply can be sourced either from

the system board or an external power source via screw terminals by selecting the appropriate setting on the

jumper block.

2 Interfacing with the Pmod

The PmodCON3 communicates with the host board via one of the four GPIO pins (the first four pins on the 1×6

header). As mentioned in the Functional Description, it is also possible to select how to power an attached servo

motor by setting the shorting block in the appropriate jumper configuration.
