Overview 

The  EVK-M8F-0-00  evaluation  kit makes  evaluating the high performance u-blox  M8  time and frequency 
reference products simple. The built-in USB interface provides both power supply and high-speed data transfer, 
and eliminates the need for an external power supply. Additionally, the dedicated EXTENSION connector in the 
EVK-M8F-0-00 provides access to time and frequency interface signals. u-blox evaluation kits are compact, and 
their user friendly interface and power supply make them ideally suited for use in laboratories, vehicles and 
outdoor locations. Furthermore, they can be used with a PDA or a notebook PC, making them the perfect 
companion through all stages of design-in projects.
