STEVAL-MKI124V1 STMicroelectronics

STEVAL-MKI124V1 L3GD20, LSM303DLHC and LPS331AP 10-axis module for a standard DIL24 socket Data brief Description The STEVAL-MKI124V1 is an adapter board designed to facilitate the evaluation of the L3GD20, LSM303DLHC and LPS331AP MEMS devices. The board offers an effective solution for fast system prototyping and device evaluation directly within the users own application. The STEVAL-MKI124V1 can be plugged into a standard DIL 24 socket. The adapter provides the complete L3GD20, LSM303DLHC and LPS331AP pinout and comes ready-to-use with the required decoupling capacitors on the V DD power supply line. Features This adapter is supported by the STEVAL- Complete L3GD20, LSM303DLHC and MKI109V2 motherboard which includes a high LPS331AP pinout for a standard DIL 24 performance 32-bit microcontroller functioning as socket a bridge between the sensor and a PC, on which Fully compatible with the STEVAL- it is possible to use the downloadable graphical MKI109V2 motherboard user interface (Unico GUI), or dedicated software RoHS compliant routines for customized applications.
