These coupling devices fit for adding a RFID HF/NFC reader/writer to any microcontroller-based product or to any embedded system with a serial interface (UART). They are able to communicate with contactless cards or compliant badges at a distance up to 10cm.And thanks to the Low Power Standby mode (LPCD), the modules can be used even with power-constrained systems.

The SpringCard K663-TTL, K6632-232 et K663-485 are made up of the K663 module linked with a 69x45mm antenna.
Communication with host is with a serial link according to your needs:

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

They only require a single 3 to 5V power supply, and support in-field firmware upgrade (available here).

Here is a presentation of the K663 TTL, 232, 485 module in video.
