Installation
Alternative Installation Options
One-wire Connect via "Floppy-disk" extension cable
If mounting the navX2-MXP circuit board directly into the RoboRIO's onboard MXP connector is not
possible, a "Floppy-disk" extension cable can be used to place the navX2-MXP circuit board up to a few
feet away from the RoboRIO. This installation method supports the I/O expansion capabilities, since all
MXP connector signals are carried over the extension cable.
Note that higher-speed signals such as those found on the SPI and I2C bus, and noise-sensitive analog
signals like those on the Analog Input and Output pins may be negatively impacted by longer distances
and electro-magnetic interference, so high quality shielded cabling and shorter distances may be called
for.
These extension cables are available online at AndyMark:

One-wire Connect via USB cable
By using a USB Mini-B type (Male) to USB A type (Male) connector, navX2-MXP can receive both
power and also communicate with the RoboRIO.
This installation method allows the navX2-MXP circuit board to be placed longer distances away from
the RoboRIO than via the "Floppy-disk" extension cable method. However, this installation method does
NOT support the MXP I/O expansion capabilities, since the MXP connector signals are not routed over
the USB cable.
Low-level Connect via Power and Signal pins on MXP Connector
If any of the "one-wire" methods described above is not desirable, you may also interface to the
navX2-MXP circuit board using the Power, Ground and I2C/SPI/TTL UART signals on the MXP
Connector.
