WARNING

Check the pinout!

The pinout of DYNAMIXEL can differ from the pinout of connector

manufacturer.

4. 4. Communication Circuit

To control the DYNAMIXEL actuators, the main controller needs to convert its UART signals to the
half duplex type. The recommended circuit diagram for this is shown below.
