STEVAL-MKI190V1 Adapter Board STMicroelectronics STEVAL-MKI190V1 Adapter Board is configured to evaluate the operation of the LISDTW12 MEMS Digital Output Motion Sensors. The LISDTW12 Sensors have an integrated 32-level first-in, first-out (FIFO) buffer allowing the user to store data in order to limit intervention by the host processor. The STEVAL-MKI190V1 Board can be plugged into a standard DIL 24 socket and provides the complete LISDTW12 pin-out. The board comes ready-to-use with the required decoupling capacitors on the VDD power supply line.
