Introduction
The purpose of this application note is to illustrate how the Kionix KMX62
accelerometer-magnetometer can replace an existing Kionix KMX61 accelerometer-
magnetometer.
Pin Compatibility
The KMX61 accelerometer-magnetometer can be replaced by a KMX62 accelerometer
magnetometer for I2C interface application.
