LIS3LV02DL adapter board
Introduction
The LIS3LV02DL adapter board is intended to provide an effective solution based on LIS3LV02DL three-axes digital output linear accelerometer that address user needs for fast system prototyping and device evaluation directly within his own application. The LIS3LV02DL adapter board has been designed to be plugged into a standard DIL 20 socket. It provides the user with the complete LIS3LV02DL pinout and comes ready to use with the required decoupling capacitors on the Vdd power supply line. The pinout of the adapter has been designed to be fully compatible with all the other adapter boards available so that the user can easily switch from one sensor to another during his evaluation without the need of board redesign. This user manual describes the LIS3LV02DL adapter board. For any detail about LIS3LV02DL specifications refer to component datasheet.
