DVK90121
General Description
The development kit DVK90121 has been developed by Melexis to create specific applications using
international standards ISO/IEC and to evaluate the advantages and the high flexibility of the MLX90121
13.56MHz multi-norms RFID transceiver.
The DVK90121 consists of the evaluation board EVB90121 connected to the RFID universal development
board. The universal development board contains the firmware for the communication with the MLX90121
and the communication with a computer through the RS232 serial interface.
A user interface software UT121, developed by Melexis, allows the user controlling the communication by
initializing the MLX90121 device, sending specific commands and receiving the corresponding reply.
