Description
The STEVAL-MKI012V1 is an evaluation kit designed to provide the user with a platform for evaluating the LIS3L02AL or the LIS3L06AL MEMS accelerometers in the LGA package with analog output. It implements a typical application composed the accelerometer and the TS924 railto-rail precision buffer. The supply voltage is generated by an LE33 voltage regulator, which ensures the correct power required by the LIS3L02AL device. All parts on the STEVAL-MKI012V1 evaluation kit board are STMicroelectronics components. STEVAL-MKI012V1
