NOTE: The MXP connector has 2 Digital I/O pins which are dedicated to the I2C interface. MXP Digital
I/O Pin DIO14 is used for I2C SCL and DIO15 is used for I2C SDA. Since the navX2-MXP I2C interface
is always active, these pins must not be used for any other purpose.
Analog Inputs
Each of the 4 Analog Input pins on the MXP connector has a corresponding 3-pin connector (DC
Voltage, Ground and Signal). On the RoboRIO, these signals are routed to the internal Analog-to-Digital
Converters (ADCs).

Analog Outputs
Each of the 2 Analog Output pins on the MXP connector has a corresponding 3-pin connector (DC
Voltage, Ground and Signal). On the RoboRIO, these signals are generated by the host computer's
internal Digital-to-Analog Converters (DACs).
