*Reading distance depends on tag, antenna and environmental conditions.

The RFID LF Embedded Module – M890 series is a module series for short range applications. Thanks to its tiny size and single-face laying components layout, it allows for embedding in various applications and devices. Especially for access control or asset tracking solutions, is this LF module applicable.

RFID LF Embedded Module – M890 series is available in 125 kHz or 134.2 kHz RFID LF Frequency range. They also support read-only EM4100, EM4200, TK4100 and FDX-B. The LF Module can create ISO/IEC 11784/11785 from Hitag-S transponders. The module supports all functions of the Hitag family. It achieves reading ranges of up to 10 cm (depending on type of transponder).

The RFID LF Embedded Module – M890 series features one external antenna port. We offer a wide choice of RFID antennas suitable for any purpose.

The Module M890 is available with TTL, USB VCP or RS232 interface. In low power mode, the M890 modules consumes less than 1 mA.

iDTRONIC’s hardware comes with a useful SDK for the development of controller, Linux or Windows based applications. Beside the documentation, command protocols and source codes, the SDK includes a Windows based demo application with full functionality over all supported HF RFID standards.
