Arduino Nicla Sense ME
Overview
The Arduino Nicla Sense ME 1 is designed around Nordic Semiconductor’s nrf52832 ARM Cortex-M4F CPU. The board houses 4 low power industrial grade sensors that can measure rotation, acceleration, pressure, humidity, temperature, air quality and CO2 levels.

Programming and Debugging
Applications for the arduino_nicla_sense_me board configuration can be built and
flashed in the usual way (see Building an Application and
Run an Application for more details).
Flashing
First, connect the Arduino Nicla Sense ME board to your host computer using the USB port to prepare it for flashing. Then build and flash your application.
Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b arduino_nicla_sense_me samples/hello_world
west flash
Run a serial host program to connect with your board:
$ minicom -D /dev/ttyACM0
You should see the following message on the console:
Hello World! arduino_nicla_sense_me
Debugging
You can debug an application in the usual way. Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b arduino_nicla_sense_me samples/hello_world
west debug
