MXP NXT Adapter for NI myRIO
- 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.
