    Hi Guys,
    I have attached an image showing how the Herkulex smart servo is connected with an Arduino uno board ( RX is pin 11, and TX is pin 10 ), how can I connect the servo to the Duet wifi ??

      Do they take step and direction pulses?

          @Phaedrux Those are RC/robot - no step/dir/enable... RS-232 serial comms only

            hi
            Yes, I have all those documents already, and have used the servos connected with Arduino uno and Arduino due.
            I just want to know how can I use them with the Duet wifi ???
            a sketch would be appreciated for the connections,
            or since I know how to connect them to the Arduino board, is it possible to use the Arduino with the duet wifi ?? if so how ??
