InstallationFTC InstallationTo ensure the +5V from the DIM is used to power the navX-MXP board circuitry, ensurethat the “Voltage Select” jumper is set to 5V.Electrical Wiring VerificationIf properly wired, when power is applied to the DIM, the Red 3.3V LED on the navX-MXP shouldlight up.Double-check that the SDA and the SCL wires on the DIM match the corresponding pins on thenavX-MXP circuit board.Physical Installation on the RobotThe navX-MXP circuit board should be mounted such that it is firmly attached to the robotchassis. The quality of this mounting will be directly reflected in the quality of navX-MXPinertial measurements. To ensure quality, carefully follow these guidelines:Whereever the navX-MXP circuit board is placed, it should be tightly mounted; it shouldbe a part of the chassis mass, and should move exactly as the chassis moves. Avoidmounting the navX-MXP circuit board in an area of the chassis that might be flexible, asthis could introduce vibration to the inertial sensors that does not represent the chassisinertial properties.The navX-MXP circuit board should be mounted in the center of the chassis, whichensures the origin of the yaw/pitch/roll axes truly represent the chassis center.Be sure to understand the orientation of the navX-MXP circuit board, relative to thechassis, and decide whether OmniMount is needed.Housing the navX-MXP circuit board in some form of protective enclosure is highlyrecommended, to protect it from damage. This should both protect the circuit board fromdamage, and provide strain relief for the cables that connect to the navX-MXP circuitboard.13
