Product overview
Description
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).
