STEVAL-MKI122V1 STMicroelectronics

STEVAL-MKI122V1 LSM330DLC adapter board for a standard DIL24 socket Data brief Description The STEVAL-MKI122V1 is an adapter board designed to facilitate the evaluation of MEMS devices in the LSM330DLC product family. The board offers an effective solution for fast system prototyping and device evaluation directly within the users own application. The STEVAL-MKI122V1 can be plugged into a standard DIL 24 socket. The adapter provides the complete LSM330DLC pinout and comes ready- to-use with the required decoupling capacitors on the VDD power supply line. Features This adapter is supported by the STEVAL- Complete LSM330DLC pinout for a standard MKI109V2 and STEVAL-MKI109V3 DIL 24 socket motherboards which include a high performance 32-bit microcontroller functioning as a bridge Fully compatible with the STEVAL- between the sensor and a PC, on which it is MKI109V2 and STEVAL-MKI109V3 possible to use the downloadable graphical user motherboards interface (Unico GUI), or dedicated software RoHS compliant routines for customized applications.
