STEVAL-MKI174V1 STMicroelectronics

S T E VA L - M K I 1 7 4 V 1 LIS2DS12 adapter board for standard DIL24 socket Data brief Description The STEVAL-MKI174V1 is an adapter board designed to facilitate the evaluation of MEMS devices in the LIS2DS12 product family. The board offers an effective solution for fast system prototyping and device evaluation directly inside the user application. The STEVAL-MKI174V1 can be plugged into a standard DIL24 socket. The adapter provides the complete LIS2DS12 pin-out and comes ready-to- use with the required decoupling capacitors on the VDD power supply line. This adapter is supported by the STEVAL-MKI109V3 motherboard, which includes a high performance Features 32-bit microcontroller functioning as a bridge Complete LIS2DS12 pinout for a standard between the sensor and a PC, on which it is DIL24 socket possible to use the downloadable graphical user Fully compatible with the STEVAL- interface (Unico GUI) or dedicated software MKI109V3 motherboard routines for customized applications.
