If you are looking for the difference between Microchip Bluetooth modules RN4678-V/RM113 and RN4678-VB/RM113, please refer to the information provided by the manufacturer below:
The ‘VB’ variant was created for customers using IS1677 family (RN4677, BM4677) to migrate to the IS1678 family (RN4678, BM78) after the xx77 family was discontinued.
Other than that, there is no difference such as form, fit or functionality between ‘V’ and ‘VB’ products.
