The V5 Robot Radio allows your V5 Robot Brain to communicate with the V5 Controller and other V5 Robot Radios. All wireless communication to the V5 Robot Brain is done through the V5 Robot Radio, including driving with the V5 Controller, competition control, and wireless downloading of VEXcode projects.
The V5 Robot Radio works in combination with the V5 Controller and can provide either VEXnet 3.0 or Bluetooth wireless control and programming.
Its narrow profile lets the Radio be mounted to your robot in nearly any location by using the two #8-32 threaded inserts and #8-32 screws. Positioning the radio where the end with the red VEX logo is near metal is not recommended as it increases the risk of radio interference.
The Smart Port is used to connect the Robot Radio to the V5 Robot Brain via a Smart Cable and is conveniently located on the end.
