## Description

## Overview

The Arduino Nicla Sense ME is a tiny (22.86×22.86mm) multi-sensor module designed for environmental and motion intelligence at the edge. It integrates four Bosch Sensortec sensors: the BHI260AP smart IMU with built-in AI for motion classification, BMM150 magnetometer, BMP390 barometric pressure sensor, and BME688 4-in-1 gas sensor measuring temperature, humidity, air quality, and CO2 levels.

Powered by the nRF52840 ARM Cortex-M4F with BLE 5.0 connectivity, the Nicla Sense ME runs sensor fusion algorithms directly on the Bosch BHI260AP's neural network accelerator, offloading motion classification from the main MCU. This architecture enables always-on activity recognition, compass heading, altitude tracking, and air quality monitoring at minimal power consumption.

Compatible with the Nicla, Portenta, and MKR ecosystems, it operates standalone on battery power or plugs into carrier boards. Ideal for wearable health monitors, environmental tracking, indoor air quality stations, and predictive maintenance sensors.
