1. Antenna Interface
1. When designing fixed reader with module, 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.
