STEVAL-MKI203V1K STMicroelectronics

STEVAL-MKI203V1K Data brief Temperature probe kit based on STCN75 Features User friendly STCN75 board Complete STCN75 pinout for a standard DIL 24 socket Fully compatible with and STEVAL-MKI109V3 motherboards RoHS compliant WEEE compliant Description The STEVAL-MKI203V1K evaluation kit consists of a probe with the STCN75 temperature sensor connected via flat cable to the STEVAL-MKIGIBV1 adapter board, so it can interface with the STEVAL-MKI109V3 motherboard. The device small package dimensions allow it to be mounted on top of a very thin probe, so it can take temperature readings not influenced by heat from other electronic components or boards. The STEVAL-MKIGIBV1 can be plugged into a standard DIL24 socket. The kit provides the complete STCN75 pinout and comes ready-to-use with the required decoupling capacitors on the VDD power supply line. The STEVAL-MKI109V3 motherboards feature a high performance 32-bit microcontroller functioning as a bridge between the sensor and a PC running the free Unico GUI graphical user interface or dedicated software routines for customized applications.
