Getting started with the STEVAL-C34KAT1 vibrometer and temperature sensor expansion kit
Introduction
The STEVAL-C34KAT1 is a multisensing expansion kit that includes the STEVAL-C34AT01 expansion board and a flexible cable.
The small form factor and the accurate design allow a precise measurement of vibrations up to the sensor bandwidth (6 kHz) as well as of the temperature.
The IIS3DWB vibration sensor is soldered at the center of the small 25 x 25 mm board. The STTS22H temperature sensor is placed on the PCB side and is thermally coupled to the PCB bottom exposed pad through vias.
The expansion board can be mounted on the equipment for the vibration analysis using the four holes or the double-sided adhesive tape. This board is compatible with the STWIN.box kit ( STEVAL-STWINBX1 ).

Precautions for use

Precautions for use
Important: This kit is not immune to indirect electrostatic discharges. During the ESD test, the kit has obtained level C. This means that the expansion board has not been damaged during the test, but the intervention of the operator was necessary to reset it. When an electrostatic discharge is applied to an adjacent object, the board might interrupt its functioning. In this case, the intervention of an operator is required to reset the board (that is, to unplug and replug the power supply line).
If the board is attached to a STEVAL-STWINBX1 (STWIN.box), you can control the power supply of the external
34-pin connector via software, by leveraging the power switch functionality of the STBC02 battery charger IC.

How to use the kit
How to use the kit
The STEVAL-C34KAT1 expansion board can be used with the STEVAL-STWINBX1 kit (STWIN.box).
The device can be attached to the STWIN.box using the provided flexible cable, through the 34-pin connectors available on both platforms.
Figure 2. Expansion board and flexible cable
To plug the flexible cable onto the STWIN.box, remove the plastic case cover.
Figure 3. Plugging the flexible cable onto the STWIN.box
You can then remount the cover, as it leaves enough space for the flexible cable.
Figure 4. Final setup
UM3021 - Rev 1
The easiest way to read data from the STEVAL-C34KAT1 sensors is to flash the STWIN.box with the FP-SNS-
DATALOG2 function pack compiled with the external sensor option. The firmware package provides a ready to use, precompiled binary.

Adhesive tape
Adhesive tape
The kit provides a few samples of 3M™ 9088 high performance, double coated tape. These samples can be used to mount the board on the equipment for vibration analysis.
Alternatively, you can mount the board through the holes located at each corner of the PCB.
The small form factor of the PCB ensures no resonances and a flat frequency response for the complete bandwidth of the sensor (up to 6 kHz).
