STEVAL-MKI108V2 STMicroelectronics

STEVAL-MKI108V2 L3GD20 and LSM303DLHC 9-axis module for a standard DIL24 socket Data brief Description The STEVAL-MKI108V2 is an adapter board designed to facilitate the evaluation of L3GD20 and LSM303DLHC MEMS devices. The board offers an effective solution for fast system prototyping and device evaluation directly within the users own application. The STEVAL-MKI108V2 can be plugged into a standard DIL 24 socket. The adapter provides the complete L3GD20 and LSM303DLHC pinout and comes ready-to-use with the required decoupling capacitors on the V power supply line. DD Features This adapter is supported by the STEVAL- Complete L3GD20 and LSM303DLHC MKI109V2 motherboard which includes a high pinout for a standard DIL 24 socket performance 32-bit microcontroller functioning as Fully compatible with the STEVAL- a bridge between the sensor and a PC, on which MKI109V2 motherboard it is possible to use the downloadable graphical RoHS compliant user interface (Unico GUI), or dedicated software routines for customized applications.
