Arduino YN is the first member of a new groundbreaking line of wifi products combining the power Linux with ease of use of Arduino.
The first Arduino YN is the combination of a classic Arduino Leonardo (based on the Atmega32U4 processor) with a Wifi system-ona-chip running Linino (a MIPS GNU/Linux based on OpenWRT). We embedded the Linux machine directly on the PCB of the Arduino Leonardo and we connected the two so that from Arduino its very easy to run commands on the Linux side and use it as an Ethernet and Wifi interface.
