Overview
The Digilent PmodCON3 Servo Connector
Module Board (the CON3™) makes it easy to
drive up to four servo motors from any Digilent
system board.
The CON3 conveys signals between a 6-pin
header and one of four servo-motor
connectors. A terminal block and jumpers are
provided so that an external motor power
supply can be used.
Features include:
• a 6-pin header connector
• four servo motor connectors
• flexible power delivery to servo motors
• small form factor (1.00” x 0.80”).
Functional Description
The CON3 can drive up to four servo motors
like those used in radio controlled airplanes
and cars. The servo motors can be powered
by 4.5V to 6V sources, while being controlled
with TTL-level logic signals.
The CON3 can be used in conjunction with
Digilent system boards and embedded
controller boards for robotics and distributed
systems.
The CON3 can be used with most servo
motors including those that deliver anywhere
from 50 to 300 ounce/inches of torque.
Servo motor power can come from a system
board (for low power applications) or from an
external power source (for higher-power
applications). A jumper setting determines the
power source.
Servo motors attached to the CON3 can be
driven individually or in groups of two or more.
Servo motors are used in a number of robotic
applications, including steering, movement,
and rotation. Servos are designed to move to a
precise desired position and then stop.
