STEVAL-MKI125V1 A3G4250D adapter board for a standard DIL24 socket Data brief Description The STEVAL-MKI125V1 is an adapter board designed to facilitate the evaluation of MEMS devices in the A3G4250D product family. The board offers an effective solution for fast system prototyping and device evaluation directly within the users own application. The STEVAL-MKI125V1 can be plugged into a standard DIL 24 socket. The adapter provides the complete A3G4250D 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- MKI109V2 motherboard which includes a high Complete A3G4250D 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 it is possible to use the downloadable graphical MKI109V2 motherboard user interface (Unico GUI), or dedicated software RoHS compliant routines for customized applications.
