This motor multiplexer (MTRMX-Nx) is specifically designed medium power motor controller to connect RCX LEGO motors to NXT.

This multiplexer connects directly to one of the digital sensor ports of NXT and the power for the motors is supplied from an external source.

It's designed as Quad 35 Volt 0.6 amps H-Bridge motor drive.

This multiplexer drives 9 volt RCX compatible Lego electric motors (Lego 71427, 74569, 43362 or Electric RC Race Buggy Motor 5292).

Use this if you already have some of these motors and wish to put them to use with NXT. If you don't have these motors, we suggest NXTMMX or NXTServo.

Note: Consult your motor power ratings before attaching motors. Under load some motors draw excessive current which can damage the controller and/or battery.

Picture 2 shows two RCX motors and one RC motor connected to the MTRMX-Nx. To conserve your main NXT batteries, the power hungry motors are supplied electricity from external battery connected to the white/black wire above.

If you wish to connect regular DC motors to this: Connect DC motors to NXTYou can connect regular DC motors (max 35 volts, 500 mA) to this MTRMX-Nx by attaching motor pins to the holes shown in adjacent picture.
