DC Voltage Selection
Using the provided jumper, select the DC Voltage which will be routed to each of the connector
blocks. Select from either 3.3V or 5V DC. This regulated voltage is supplied directly by the host
computer (e.g., the RoboRIO).
I/O Summary
Each of the I/O pins on the MXP connector has a corresponding 3-pin connector (DC Voltage,
Ground and Signal). The orientation of the Ground, Power and Signal pins for each of the
Digital I/O, Analog Input and Analog Output pins is as follows:
Digital I/Os
Each of the 10 Digital I/O pins may be configured for use as either DigitalInputs or
DigitalOutputs, PWM (Outputs) or Counters (Inputs).
Additionally, multiple (either 2 or 3) DigitalInputs may be used to form an QuadratureEncoder
input.
