Arduino Yun




$71.95 ea.

Take a wireless router-on-a-chip, and stick an Arduino Leonardo to it - that's the new Arduino YUN!

Description [Hide]

Arduino is fine on it's own, but when you want to make it talk to the "cloud" you'll find there's many, many paths to try out. The team at Arduino has streamlined this task into the the Arduino Yún. Perfect for data logging and IoT applications.

Combine a standard Arduino Leonardo (running an ATmega32u4) with a chip (Atheros AR9331) that offers an embedded Linux router with Ethernet and WiFi ability, then shoe-horn it into a standard Arduino-sized footprint. All the communications heavy lifting is done by the Atheros chip, leaving all the standard I/O pins free to the Arduino!

It's a clever system, where you can still use the same Arduino programming environment to use the advanced internet abilities of the Yún.

Special to the Yún is the auto-discovery system, where your PC can recognize boards connected to the same network, letting you upload sketches via the network (in addition to the regular micro-USB connector).

Connectivity Features

Yún's networking features include:

  • WiFi IEEE 802.11 b/g/n 2.4GHz
  • WiFi WEP, WPA and WPA2 encryption
  • WiFi Access point mode capable, where any WiFi device can connect to the Yún's network (but not bridged to the internet)
  • The Ethernet interface is also fully featured, with a 10/100 Mbit/s ethernet port.
  • Temboo web-connectivity for interfacing the Yún to many online tools

Other Funky Features

  • The embedded router features a full Linux distribution ("Linino" - OpenWRT variant) with a full python installation and package manager.
  • The Atheros chipset has 64MB of DDR2 RAM, so webservers and webcam video streaming is possible with this powerhouse!
  • Add an microSD or USB thumbdrive for even more storage space.
  • There's a USB host port for connecting that (above mentioned) thumbdrive, webcam, etc. Mindboggling what's available on this board.
  • Power-over-Ethernet is possible with the 5V PoE module (do not use with the regular 12V model)

Technical Specifications:

  • ATMega 32u4 (16MHz) & Atheros AR9331 controllers
  • 5VDC operating voltage
  • 20 digital I/O, 7 PWM pins
  • 12 Analog input pins
  • 40mA current limit per pin
  • 50mA limit from 3.3V source pin
