Improvements and Features

The new firmware v5.34 has various improvements and features listed below:

Updated internal electrical components for part obsolescence.
Improved internal components have no impact on the performance of the GNSS receivers.
Improved GNSS receiver with the new internal components may be used with older MS9x5 and MS9x2 GNSS receivers, although most dual receiver systems require matching GNSS firmware across receivers.

Note: The MS9x5 GNSS receivers with the new internal components cannot be downgrade to GNSS receiver firmware older than v5.34.
