Where can I find software support for the Intel Curie module?

Visit the Intel Curie module community forum or see the Intel® Curie™ Open Developer Kit (ODK)




Where can I have my own reference board built?

A local contract manufacturer or international service can build your reference and accessory boards. Some of them offer help with custom layouts to fit your exact needs. Premier Farnell has been enabled by Intel to provide support, and other partners are in the process.

Can I purchase an assembled and tested reference board?

Intel is working with Arduino* on the Arduino 101 board and Premier Farnell on the tinyTILE board to make such boards available.

What is the difference between Arduino 101 and Genuino 101*?

Genuino 101 is the brand name in some countries for the Arduino 101 board. There is no technical difference.

What is the physical size of the Arduino 101?

The Arduino 101 board measures 68.6 mm x 53.4 mm.

What is the physical size of the tinyTILE?

The tinyTILE board measures 36 mm x 26 mm x 5 mm, rounded up.

What if I have questions about my reference board?

Contact your reference board vendor for support.

How do I download my software to the Intel Curie module?

USB Device Firmware Upgrade (DFU) is the most common interface used to send commands and programs to the Intel Curie module. Other communication methods are also supported to a varying extent. For example, you can flash your code via JTAG, using Flyswatter2 or J-Link.

To download the Bluetooth block, refer to the Nordic Semiconductor website.

How can I program the Intel Curie module if I don't have a USB in my design?

A JLINK EDU or Flyswatter2 JTAG programmer can be used to program software for the Intel® Quark™ SE C1000 microcontroller, including Bluetooth® low energy firmware.

How can I meet input voltage requirements when using a battery source?

Please refer to the Intel Curie Module Design Guide for information on this topic.

Do I get lower power consumption using 1.8 V or 3.3 V supply (both are valid options)?

In general:

  • The lower-voltage design choice will have lower power consumption and will generate lower signal noise.
  • Depending on your selection, make sure the hardware design should follows datasheet and reference design guide recommendations. This ensures the design meets all interface signal-level requirements between the functional blocks.

For example, if you use a 1.8 V I/O voltage for the Intel Quark SE processor, be sure the Bluetooth low energy sub-system is also running at 1.8 V I/O voltage.




Is power management supported on the Intel Curie module?

Yes, the Intel Curie has advanced power management functionality. The extent of support depends on the software being used.

Can I use an integrated development environment (IDE)?

Yes. The Arduino IDE is available for boards that are compatible with the Intel Curie module. This includes Arduino 101/Genuino 101 and tinyTILE boards. The Intel® Curie™ Open Developer Kit (ODK) is a command-line environment. You can configure your own tools to work with it.

How much memory and storage is available for an Arduino sketch?

24 KB of SRAM and 196 KB of flash memory is available for an Arduino sketch.

What software do the Arduino 101 and tinyTILE platforms support?
