Using the VEX GO Brain – VEX Library

Using the Brain allows you to bring the VEX GO system to life by programming Motors and Sensors with VEXcode GO.

Connect a Battery to the Brain

Battery with its connection cable plugged into the Battery Port on a Brain.

The Brain will not work without a Battery.

Next, locate the orange Battery Port on the Brain.

Brain with a Battery Cable plugged into its Battery Port to power the Brain.

Connect the Battery to the Brain by inserting the orange Battery Cable into the orange Battery Port on the Brain.

Diagram of two Brains with Battery Cables plugged into their Battery Ports to power them. On the left the Battery Cable is plugged in fully and there is a green check mark, while on the right the Battery Cable is only plugged in partially and there is a red X.

Ensure that the orange Battery Cable is fully inserted into the orange Battery Port on the Brain. A ‘click’ sound will ensure that the cable is seated fully into the port.

Turn On the Brain

Brain with its power button highlighted in a red box. The power button is located in the center of the top side of the Brain.

Once the Battery has been connected to the Brain, the Brain can now be turned on.

To turn on the Brain, press the clear button with an orange ring around it on top of the Brain.

Brain with its power button highlighted in a red box and glowing green to indicate that the Brain is powered on.

The clear button will turn green when the Brain is powered on.

Turn Off the Brain

To turn off the Brain, hold the green button on top of the Brain for approximately three seconds.

Brain with its power button highlighted in a red box. The power button is not glowing green, indicating that the Brain is powered off.

Once the Brain is powered off, the button on top of the Brain will no longer be green.

Connect Motors and Sensors to the Brain

Brain with its row of 4 Smart Ports highlighted in a red box.

There are four Smart Ports at the top of the Brain where the LED Bumper, Electromagnet, and Motors are connected.

Brain with its orange Battery Port highlighted.

On the opposite side of the GO Brain are additional ports colored orange and blue-green. The orange Battery Port is for connecting the Battery as seen above.

Brain with its blue-green Eye Sensor Port highlighted.

The blue-green Eye Sensor Port is designated to connect the Eye Sensor.

Motor with its cable plugged into one of the Brain's Smart Ports.

Connect the LED Bumper, Electromagnet, or Motors to the Brain by inserting the device cable into one of the four Smart Ports on the Brain.

Diagram of two Brains with device cables plugged into their Smart Ports. On the left the device cable is plugged in fully and there is a green check mark, while on the right the device cable is only plugged in partially and there is a red X.

Ensure that the device’s cable is fully inserted into the Smart Port on the Brain. A ‘click’ sound will ensure that the cable is seated fully into the Smart Port.
