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.

Hardware

  • nRF52832 ARM Cortex-M4 processor at 64 MHz

  • 512 kB flash memory, 64 kB SRAM

  • Bluetooth Low Energy

  • Micro USB (USB-B)

  • JST 3-pin 1.2 mm pitch battery connector

  • 10 Digital I/O pins

  • 2 Analog input pins

  • 12 PWM pins

  • One reset button

  • RGB LED (I2C)

  • On board sensors:

    • Accelerometer/Gyroscope: Bosch BHI260AP

    • Gas/Pressure/Temperature/Humidity: Bosch BME688

    • Geomagnetic: Bosch BMM150

    • Digital Pressure: Bosch BMP390

Programming and Debugging

The arduino_nicla_sense_me board supports the runners and associated west commands listed below.

flash debug

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
