STMicroelectronics STEVAL-C34KAT2 iNemo Inertial Module

Product Information

The STEVAL-C34KAT2 is an expansion kit designed to be used with the STEVAL- STWINBX1 evaluation board. It features the iNEMO inertial module with embedded ISPU (ISM330IS) and a temperature sensor. The kit includes the expansion board and a flex cable for connecting it to the STWIN.box.

Key Features

• Ideal plug-in for the STEVAL-STWINBX1 evaluation board
• iNEMO inertial module with embedded ISPU (ISM330IS)
• Exposed pad on the bottom side to improve thermal coupling for the temperature sensor
• 1.8 to 3.3 V power supply input

Precautions for Use

It is important to note that this kit is not immune to indirect electrostatic discharges. During the ESD test, the kit has obtained level C, meaning that it has not been damaged during the test but may require intervention from the operator to reset it in case of electrostatic discharge. If the board is attached to a STEVAL-STWINBX1 (STWIN.box), the power supply of the external 34-pin connector can be controlled via software using the power switch functionality of the STBC02 battery charger IC.

Product Usage Instructions

1. Attach the STEVAL-C34KAT2 expansion board to the STWIN.box using the provided flex cable. Connect the 34-pin connectors available on both platforms.
2. To plug the flex cable onto the STWIN.box, remove the plastic case cover. Then, plug in the flex cable and remount the cover, leaving enough space for the flex cable.
3. To read data from the STEVAL-C34KAT2 sensors, flash the STWIN.box with the FP-SNSDATALOG2 function pack. This firmware package provides a ready-to-use, precompiled binary for sensor data acquisition.
4. When removing the flex cable, be careful not to damage it. Use tweezers to safely pull it next to the connectors.
5. The kit includes samples of 3MTM 9088 high-performance, double-coated tape. These can be used to mount the board on equipment for vibration analysis. Alternatively, the board can be mounted through the holes located at each corner of the PCB.

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).

  • Operating temperature -40 to +125°C
• Exposed pad on the bottom side to improve the thermal coupling for the temperature sensor
• 1.8 to 3.3 V power supply input

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

• 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.

• To plug the flex cable onto the STWIN.box, remove the plastic case cover.

• You can then remount the cover, as it leaves enough space for the flex cable.

• 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.
  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.
