Arduino 101

The Arduino 101 is a development board from Intel based on the Intel Curie module. The Intel Curie is a Bluetooth Low Energy module built around the Intel Quark SE microcontroller that integrates compute, sense, awareness, connectivity and a programmable input/output controller within a common package. The Intel Curie is also one-for-one compatible with the Arduino SDK.

Project Specifics

There are no imported sensors or specialized elements or tools native to Arduino 101 projects.

Intel Curie products have been discontinued by their manufacturers, so support for the Arduino 101 within Atmosphere is deprecated and new projects can no longer be created with it.

Hardware Specifics

Some devices may have limitations or design restrictions that cause unexpected behavior when used with Atmosphere. Specific information and details pertaining to the Arduino 101 and its performance on Atmosphere is noted below.

  • The Arduino 101 does not have PWM support

Default Pin Mapping

Atmosphere configures each peripheral to a default pin for every supported device, based on ideal pairing of pins and their usage. The default pin configuration is set for convenience and enables each peripheral to work naturally without needing to be modified.

All pins can be used as general purpose input/output (GPIO) unless otherwise specified.

Arduino 101 projects start with the following pin configuration:

Internal Arduino 101 Pins

The Arduino 101 is compiled using the Arduino SDK, so any functions and pin mappings can also be used within Atmosphere Studio.

The default pin for any peripheral can be changed within an element's properties, from an element that references that particular peripheral.


Below is information regarding the Arduino 101’s exposed peripherals.



This I2C bus is exposed via the SDA and SCL pins on the Arduino header.



This SPI bus is exposed via the MOSI, MISO, and CLK pins on the Arduino SPI connector.


UART1 (USB Debug Console)

This UART is exposed via the USB connector.


The Arduino 101 does not have PWM support.

Programming Method

Programming the Arduino 101 involves using the programmer interface in Atmosphere Studio to install embedded firmware.

Setup Configuration

Prior to programming an Arduino 101, ensure you have the following setup configuration:

  • The Arduino 101 is connected to the computer via USB to an available communication port.
  • The computer has the necessary connectivity protocols enabled (Bluetooth Low Energy, Wi-Fi, etc.).
  • The Atmosphere IoT Agent is installed on the computer and running. This is a local application that runs in the system tray and acts as an intermediary between the computer’s connectivity protocol drivers and the browser running Atmosphere.
  • An Internet connection is maintained.
  • The project to be programmed has been compiled.

Programming Instructions

With setup complete, you can program the Arduino 101:

  1. From Atmosphere Studio’s Embedded tab, click the Program Firmware button from the tab’s toolbar. This displays the Program Firmware window.
  2. Under Device Port, select the communication port the device is connected to.
  3. Click Program to start programming. When complete, you’ll be notified that the device is programmed with the project’s embedded firmware.

When complete, the Arduino 101 is programmed with the project’s embedded firmware.
