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, you can access the 3.3 or 5V power directly from the myRIO MXP connector. The silk screen is labeled on the 6 pin breakout header to reflect the Multiplexer inputs.
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 signal pins.
