Yún Rev2-board

Yún Rev2

End of Life

The Yún Rev2, Linux powered board with the Arduino simplicity, is the perfect board for your IoT projects!

pinout

The Yún Rev2 has the power of a Linux based system that enables advanced network connections and applications. Connecting to your Wi-Fi or wired network is simple thanks to the Yún Web Panel and the dedicated YunFirstConfig sketch. The Web panel allows you to manage your shield preferences and upload your sketch. The Yún Rev2 uses the Bridge library and so extends the board capabilities by using the Linux processor.

Core
ATmega32U4

The ATmega32U4 executes powerful instructions in a single clock cycle, achieving throughputs approaching 1 MIPS per MHz allowing the user to optimize power consumption versus processing speed.

Microcontroller
Atheros AR9331

The Atheros AR9331 is a highly integrated and cost effective 2.4 GHz System-on-a-Chip (SoC) for wireless local area network (WLAN) AP and router platforms.

Connection
Internet connection

The Yún Rev2 board allows you to connect to the internet using the onboard WiFi or Ethernet connection.
