NXT Sensor Adapter for myRIO

Overview

With the NXT Sensor Adapter for myRIO, you can now connect your myRIO to the expansive NXT sensor options offered for the myRIO and LEGO® MINDSTORMS® NXT ecosystems. The NXT Sensor Adapter is designed to work with any NXT sensor under 9V, and uses an I2C multiplexer to create access to all three NXT ports using the single myRIO I2C interface included on the default FPGA personality. The NXT sensor connector signals are also available on 6-pin headers for direct access for probing or debugging.

Features Include:

Uses the myRIO Expansion Port (MXP) connector. http://zone.ni.com/reference/en-XX/help/373925A-01/myriohelp/myrio_connector_pinouts/.
Supports both passive and digital NXT sensors (under 9V)
3 LEGO® MINDSTORMS® NXT sensor connectors and standard 6 pin female breakout allowing direct access to single pins.
No external power required.
Standard 34-pin female breakout allowing direct access to all myRIO MXP connector signal pins.
