This EZ-B v4.x/2 Comm Upgrade is the latest communication board to upgrade older EZ-B v4's purchased before August 2016. The upgrade consists of a single PCB that can be swapped to replace previous communication board versions of EZ-B v4's. This next generation communication board introduces super fast communication between the robot and your PC/Mobile device.

*Note: Verify in EZ-Builder the current EZ-B v4 comm version to see if this upgrade applies to you. After connecting to your EZ-B v4, look in the popup status window at the bottom of the screen, or add the Debug control. The EZB v4 version will be displayed in the connection debug log.
