Onboard sensors
There are three MEMS sensors available onboard and another four sensors located in the U5 AmbiMate
sensor module (2314277-1) in the evaluation kit. These sensors are controlled through the I2C peripheral
bus from either the nRF52840 or nRF9160 device in the AVT9152 module. Jumper J3 allows this selection
to be made.

MEMS 3-axis linear accelerometer sensor
The MEMS 3-axis ultra-low power linear accelerometer, U2 used in the AVT9152 evaluation kit is from ST
Microelectronics (LIS2DH12). The LIS2DH12 has user-selectable full scales of ±2g/±4g/±8g/±16g and is
