Scope
The MLX90129 from Melexis is a sensor IC with an integrated 13.56 MHz high frequency (HF) interface
that allows sensor data to be read with a HF radio frequency identification (RFID) reader. The DVK90129
is a development kit designed to assist developers explore the features of the MLX90129.
This user manual provides guidelines for use of the DVK90129 development kit. It also provides
guidelines for the EVB90129 datalogger / sensor tag based on the Melexis 90129 sensor IC and the
Proxima RF USB HF RFID Desktop reader. The DVK90129 development kit along with user friendly
evaluation software will decrease sensor IC evaluation time to improve your development cycle and time
to market. The dedicated Application Programming Interface (API) provides a quick start for developing
custom applications.

Pre-programmed settings for the EVB90129
sensors along with external memory help
developers discover and apply features found in
the MLX90129 sensor IC. The XML based
configuration file and export tools allow users to
characterize the sensors and fine tune the
MLX90129 settings and share these settings
with other users. This documentation gives
instructions for software and USB reader
installation plus
guidance on features found in
the evaluation software to help developers
practice with the tools. Finally, step-by-step
instructions are given for two examples so
developers can walkthrough trial applications.
The first example is based on a sensor tag
application and the second example is based on
a datalogging application.
