STEVAL-MKI108V2
L3GD20 and LSM303DLHC 9-axis module for a standard DIL24
socket
Data brief
Features
Complete L3GD20 and LSM303DLHC
pinout for a standard DIL 24 socket
Fully compatible with the STEVAL-
MKI109V2 and STEVAL-MKI109V3
motherboards
RoHS compliant
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 user’s 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 VDD power supply line.
This adapter is supported by the STEVAL-
MKI109V2 and STEVAL-MKI109V3
motherboards which include a high performance
32-bit microcontroller functioning as a bridge
between the sensor and a PC, on which it is
possible to use the downloadable graphical user
interface (Unico GUI), or dedicated software
routines for customized applications.
