Installation
FTC Installation
Connect the Power (+), Data (SDA), Clock (SCL) and GND pins to the corresponding pins on the
navX2-MXP External I2C Port Connector.
The Harness wires are colored as follows:
Black: Ground
Red: Power
Yellow: SDA
Blue: SCL
NOTE: Although the navX2-MXP is typically powered via 5VDC when used with the RoboRIO,
navX2-MXP is fully 3.3V compatible, and thus may be powered via the Expansion or Control Hub.
Electrical Wiring Verification
If properly wired, when power is applied to the Expansion or Control Hub, the Red 3.3V LED on the
navX2-MXP should light up.
If trouble occurs communication with the navX2-MXP, double-check that the SDA and the SCL wires on
the Expansion Control Hub match the corresponding pins on the navX2-MXP.
Physical Installation on the Robot
The navX2-MXP circuit board should be mounted such that it is firmly attached to the robot chassis. The
quality of this mounting will be directly reflected in the quality of navX2-MXP inertial measurements.
To ensure quality, carefully follow these guidelines:
Whereever the navX2-MXP circuit board is placed, it should be tightly mounted; it should be a
part of the chassis mass, and should move exactly as the chassis moves. Avoid mounting the
navX2-MXP circuit board in an area of the chassis that might be flexible, as this could introduce
vibration to the inertial sensors that does not represent the chassis inertial properties.
The navX2-MXP circuit board should be mounted in the center of the chassis, which ensures the
origin of the yaw/pitch/roll axes truly represent the chassis center.
Be sure to understand the
orientation
of the navX2-MXP circuit board, relative to the chassis, and
