Prototyping
Melexis offers an MLX90314 (same demoboard and
software as the MLX90308CAB) evaluation kit which
contains an evaluation circuit board, serial interface
cable, and software diskette. The circuit board
provides
the
necessary
circuitry
for
all
three
applications circuits shown on this page. Also
included in the circuit board is level shifting and glue
logic necessary for RS-232 communications.
The board has a socket with a single MLX90314
installed, and direct access to the pins of the IC. The
user can easily attach bridge sensor to the board for
in-system evaluation.
The serial interface cable
connects the evaluation board directly to a PC’s
serial port for in-system calibration.
The software runs in the familiar Windows platform
and allows for programming and evaluation of all
