Arduino Tian

The Arduino Tian unleashes the power of a small computer running Linux, connected to a 32-bit microcontroller. The Tian is the next logical iteration of the Arduino Yun, upgrading both the microcontroller and microprocessor, and even featuring onboard Bluetooth 4.0! The Arduino Tian is an amazing way to incorporate the ease of Arduino into your next IoT project.

The Arduino Tian board is powered by Atmel’s SAMD21 MCU, featuring a 32-bit ARM Cortex® M0+ core and a Qualcomm Atheros AR9342, which is a highly integrated MIPS processor operating at up to 533MHz, and feature-rich IEEE802.11n 2x2 2.4/5GHz dual-band WiFi module. Qualcomm Atheros MIPS supports a Linux distribution, based on OpenWRT named Linino. The Arduino Tian also has a built-in 4GB eMMC memory. It is possible to switch ON/OFF the Linux port from the MCU to reduce the power consumption.

Arduino Tian Product Help and Resources

Antenna connector type?

The antenna connector on the Yun, Tian and Yun Industrial boards are a Murata SWF connector. We don't currently have a source for an adapter for these unfortunately. More information can be found on this Murata page.

    Sparkfun, take this thing out of circulation. I purchased this not knowing this was the bastard child of a feud between some of the original founders of Arduino. Looks like is now absorbed back under the umbrella (all the way back in July) and can't find ANY support forums on this. doesn't have any threads, so if they don't have them by now they probably never support it. Right out of the box from you guys none of the Bridge functionality to pass data between the micro and linux side works (100% why people would buy this). The Linino site does not look active at all and the downloads section has been down for days. Cool, I bought a linux machine that has a microcontroller on it that can't talk to each other.

      We're looking into this to see if we can find some support. Check out and keep checking our documents link for more information. We'll also consider taking this out of circulation. Thanks for your feedback.

    Just received this, and I am unable to get any of the Bridge examples to work. Has anyone had any luck without having to work magic? The sketch freezes at Bridge.begin() and the all the solutions that pertain to the Yun do not seem to fix it.

    Does the big processor supports bare metal code? Or just Linux?

    I've done some searching, but can't seem to find even a high-level answer to a big question I have before I can buy a Tian. I see how to get it to pair to Bluetooth peripherals via Linux, but can the Arduino code access input from the Bluetooth devices?

    I have a pretty complex, Arduino-based robot that I need to automatically pair to multiple Bluetooth controllers when turned on. Then I need the Arduino to trigger motors and servos and send serial commands to other devices based on input from those Bluetooth controllers.

    All I need is some kind of "hello world" example where a Bluetooth device can pair with the Tian and talk to the Arduino side.

    Very open to alternative products. I really just need an Arduino-based Bluetooth host that can pair itself to fixed peripherals.

    For Arduino Tian, could you supply a link to a detailed description of the analog and digital ports provided.

    I am looking to build my third generation of atmospheric CO2 meter. I need a description of the Tian so I can walk through my laundry list of add on boards and determine if I can actually connect each of them to the Tian.

    After understanding the hardware matchup, then I would like to read about how the software side of the two devices. I have already reached the point where programming time exceeds workbench hardware time.
