The K663/RDR-TTL, K663/RDR-232 and K663/RDR-485 modules include the antenna: they are then the ready-to-use version of the K663/RDR module.

Their size is small (69x45mm antenna) but they are able to communicate with contactless cards or compliant badges at a distance up to 10cm.

Designed to be easily integrated, they require only a single 3 to 5V power supply, and support in-field firmware upgrade. Thanks to the Low Power Card Detection (LPCD) mode, the K663/RDR can be used even in power-constrained systems.

Communication with host is ensured thanks to a serial link. The product name then depends on the kind of link:

  • K663/RDR-TTL: RX/TX serial link at TTL level (0-5V) communication, in comliance with CMOS (0-3V)
  • K663/RDR-232: RX/TX serial link at RS-232 level (EIA 232 : -6/+6V) communication
  • K663/RDR-485: RS-485 (EIA 485) half-duplex serial communication
