Many VEX V5 products contain their own internal processors and run on a special Operating System. This software is the VEX V5 Firmware and is called VEXos.

Note: VEXcode V5 can only update the firmware on the V5 Brain when connected to a device via a USB cable. VEXcode V5 does not support updating the firmware on the V5 Brain when using an iPad, Android, or Fire tablet.


What is Firmware?

This Operating System is written entirely by VEX Robotics, and harnesses the flexibility and power of VEX hardware for the diverse needs of education and the rigors of competition. The Brain will automatically push out the latest updates to any V5 device that is connected to it.


Why Should I Update? 

There are several reasons why you should update your VEX V5 Brain’s firmware with the latest VEXos, some of these include:

  • Each update of VEXcode V5 will require the latest version of the VEXos firmware installed on the brain before user programs can be downloaded.
  • VEXos updates will include fixes for known bugs and add the software which is needed to operate any new devices introduced into the VEX V5 line.
  • Updates allow for advanced programming features.
  • The best way to ensure that your VEX V5 system is functioning properly is to keep the software up to date.
  • To access the Battery Medic for the V5 Battery.
