- Two user assignable relays, two 1/2 amp 5 volt outputs and an analog input port.
- All power inputs are reverse polarity protected.
- All power outputs are current limited.
- All logic inputs and outputs are ESD protected.
- All PX4IO boards use positive retention DF13 connectors and a variety of connectors.
