RFID LF Embedded Module – M900
is a small module for short range applications. Thanks to its tiny size and one-sided components layout, the M900 allows for embedding in various applications and devices. This LF module is especially suited for access control or asset tracking solutions.

The RFID LF Embedded Module – M900 is available in 125 kHz or 134.2 kHz RFID LF Frequency range. It also supports read-only EM4100, EM4200 and TK4100. M900 LF supports all functions of the Hitag family and achieves reading ranges of up to 10 cm (depending on type of transponder).

RFID LF Embedded Module – M900 features one external antenna port. We offer a wide selection of RFID antennas suitable for any purpose.

The Module M900 is available with an TTL interface. In low power mode, the M900 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 LF RFID standards.
