The HY-R540E module supports the ISO18000-6C/EPC C1G2 protocol. Users can interconnect and communicate with their own devices through the UART-TTL pin on the interface. Its wide power supply range (DC4.5V~5.5V) can provide users with more choices. Due to the module’s good card reading distance and multi-antenna design, it can be used as a design solution for small readers and writers.
