Arduino Yun Rev 2 / ABX00020

TheArduino Yun Rev 2 is a board designed on an 8-bit ATmega32U4 microcontroller and a Qualcomm Atheros AR9331 processor. The Atheros processor supports the Linux distribution based on OpenWrt called LininoOS. The board has built-in 802.3 10/100Mbps Ethernet and Wi-Fi® 802.11b/g/n 2.4 GHz, making it ideal for designing IoT (Internet of Things) applications. The Yún Rev 2 utilizes the Bridge library, which extends the functionality of the microprocessor by utilizing the processing power of the Linux processor.

Main features:

• The ATmega32U4 executes powerful instructions in a single clock cycle, achieving throughput approaching 1 MIPS per MHz, allowing the user to optimize power consumption based on processing speed.
• The Atheros AR9331 is a highly integrated and cost-effective 2.4GHz system-on-chip (SoC) for AP and router platforms in wireless local area network (WLAN) applications.
• The Yún Rev2 board allows you to connect to the Internet using an integrated Wi-Fi or Ethernet connection.
