The Control () and Expansion Hub () were designed with a number of protection features built into the device. These include the following:

  • Reverse battery input protection

  • Electrostatic discharge (ESD) protection on all connections

  • Over-current protection on all power buses

    • Digital I/O bus

    • I2C bus

    • Analog bus

    • USB

    • Servo bus per pair (0-1, 2-3, 4-5)

    • Encoder bus

  • Over-current monitoring for individual Motor Channels

  • Keyed and locking connectors

  • Fail-safe mode at communication loss
