SpringCard K663 module is designed to be the core of a 13.56MHz reader/writer communicating in a serial link with its host (microcontroller ou embedded system).
The module needs an antenna :
- either balanced
- or 50Ω unbalanced antenna.
It depends on your size constraints or the type of tag to support (see in our antennas portfolio or ask for a custom-made one).
The module only needs to be powered in 3 up to 5V and can be updated without being stripped down (firmware upgrade is available here). Communication with host is made with a RX/TX serial link at TTL level (0-5V), in compliance with CMOS (0-3V). Thanks to the Low Power Standby mode (LPCD), the host can sleep until the coupling device gives the information that a card is shown. See a video (1'08) explaining the LPCD.
