What is NXTMMX-v2
NXTMMX is a multiplexer to
control additional NXT (or
EV3) Motors from your NXT
or EV3.
Connections and Placement
NXTMMX can be connected to any of the four sensor ports of NXT
or EV3 by using standard cables from NXT set, or FlexiCable from
mindsensors.com.
Connect your motors to ports specified as M1 and M2.
Connect NXT or EV3 to port specified as ‘NXT’.
Additional Digital Sensors (or another NXTMMX) can be connected
to port specified as ‘Sensor’.
NOTE
Port specified as ‘Sensor’ on NXTMMX only supports I2C or Digital
sensors or multiplexers.
If you intend to daisy chain several NXTMMX’s or other digital
sensors, please read the relevant section from the Advanced
Information Appendix of this doc.
Mounting NXTMMX on your contraption
The holes on the NXTMMX enclosure are designed for
tight fit of Technic pins (or axles) with ‘
’ cross section.
The holes however are not designed for repeated
insertions/removals of these pins.
To mount NXTMMX on your contraption we suggest that you use two
dark gray ‘Technic Axle 3 with Stud’ as shown.
Insert axles from the top of the device and secure with a bushing on
the back or mount it on your contraption directly.
Alternately, you may use blue ‘Technic Axle Pin with
Friction’, as shown.
While disassembling contraption, leave the pins on the device.
Supplying power to your NXTMMX
The NXTMMX has Green terminals to connect external battery.
