Arduino Yún

Arduino Yún

The Arduino Yún is a recent board from Arduino and the second to use a non-ATmega MCU, in this case it is actually the second MCU, which controls the ethernet and WiFi that is different. They are controlled by an Atheros 9331 SoC (System On a Chip), with a MIPS 24K running Linux at 400MHz. The "main" microcontroller is an ATmega32U4.

Does it mean anything when the "peripheral" controller has 4 times the data path and 25 times the speed of the "main" controller? Is there a point where you say, "Let's drop the ATmega and just use the Atheros."? If there is, then this board has passed it by. What's next..? Intel making Arduinos?
