Getting started with the STEVAL-C34KAT2, iNemo inertial module with
embedded ISPU and temperature sensor expansion kit
Introduction
The STEVAL-C34KAT2 is a multisensing expansion kit that includes the STEVAL-C34AT02 expansion board and a flex cable.
The ISM330IS 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 ISM330IS is a system-in-package featuring a 3-axis digital accelerometer and a 3-axis digital gyroscope, boosting
performance at 0.59 mA in high-performance mode and enabling always-on low-power features for optimal motion results in
industrial and IoT solutions.
The ISM330IS embeds a new ST category of processing intelligent sensor processing unit (ISPU) to support real-time
applications that rely on sensor data.
The ISPU is an ultra-low-power, high-performance programmable core, which can execute signal processing and AI algorithms
in the edge. The main benefits of the ISPU are C programming and an enhanced ecosystem with libraries and third-party tools/
IDE.
Its optimized ultra-low-power hardware circuitry for real-time execution of the algorithms is a state-of-the-art feature for any
wireless sensor node from small equipment or accessories to enterprise solutions for industry 5.0 (anomaly detection, asset
tracking, factory automation).
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-C34KAT2 expansion board can be used with the STEVAL-STWINBX1 kit (STWIN.box).
The device can be attached to the STWIN.box using the provided flex cable, through the 34-pin connectors
available on both platforms.
Figure 2. Expansion board and flex cable
To plug the flex cable onto the STWIN.box, remove the plastic case cover.
Figure 3. Plugging the flex cable onto the STWIN.box
You can then remount the cover, as it leaves enough space for the flex cable.
Figure 4. Final setup
The easiest way to read data from the STEVAL-C34KAT2 sensors is to flash the STWIN.box with the FP-SNSDATALOG2 function pack. The firmware package provides a ready to use, precompiled binary to perform sensor
data acquisition.

How to use the kit
Note:
Please be careful when you remove the flex cable as you may damage it. The safest way to remove it is by
pulling it next to the connectors using tweezers.

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.
