STEVAL-MKI238A Adapter Board STMicroelectronics STEVAL-MKI238A Adapter Board implements the evaluation of the LIS2DUX12 MEMS devices. The LIS2DUX12 ultra-low-power accelerometer is a smart, digital, 3-axis linear accelerometer. The STEVAL-MKI238A board offers fast system prototyping and device evaluation directly within a user’s application. The STEVAL-MKI238A plugs into a standard DIL 24 socket. The board supplies the complete LIS2DUX12 pinout and embeds the needed decoupling capacitors on the VDD power supply line.
