# B3RB Naming and Versions

## Overview

MR-B3RB is a kit of kits. That means it is built up as a series of other part numbers that are packaged together to define few different sub-kits and final kits. This allows for a mix and match approach internally to provide few different final variants.\
\
Only the final part numbers are available for sale on NXP.com, but you may find references to the sub-kits and internal kits in the documentation. In case this becomes confusing, we thought it best to explain the internal and external names here. 

Most Mobile Robotics part numbers/name will start with "MR-"

## Internal part kit names

The following part number/naming are internal and not normally for sale separately.
