EVB90129
MLX90129 Evaluation Board
5.4 Test points and patch area
Some analogue outputs are foreseen on the evaluation board as test pins referenced from TP1 to TP4. These
test pins can be used to monitor signals. In order to connect other sensors to the MLX90129, a patch area is
available. The following table describes all test pins available and the following schematic shows the signals
available on the patch area.

The EVB90129 can be configured and controlled through its RFID and its SPI interface. Please refer to the
MLX90129 Datasheet and the application notes for information about register configuration and command
description. A bad configuration can lock the MLX90129 communication completely. Care should be taken
about the command sent and the configuration applied. In order to avoid bad manipulation and to speed up the
development, the MLX90129 development kit is available (DVK90129). It contains the EVB90129, a USB RFID
reader and user friendly software interface. Please refer to our website (www.melexis.com) for more
information.
