Application Information

1. When designing fixed reader with CF-MU808, please take care of heat sinking and remember to make sure the heat sinker of the module is closely and stably attached to the reader’s bottom plate;

2. ANT1 is the default antenna port. Please pay attention to antenna port’s definition.

 

3. Please refer to CF-MU808 user’s manual for detailed protocol description.
