Arduino Nano 3.0 now available for pre-order (upgraded and cheaper)
We’re happy to announce that a new and improved version of the Arduino Nano is now available for pre-order. The Nano is an all-in-one Arduino board perfect for use with a breadboard; just connect a mini USB cable. The Arduino Nano 3.0 includes the ATmega328 microcontroller, which provides twice the memory of the previous ATmega168. The new board is only $35 (down from $50). If you pre-order from the manufacturer (Gravitech), the cost drops to only $30. Orders will ship on July 27th.
Other changes include: the power LED has moved to the top of the Nano, the pin labels have been rearranged for easier use, and the PCB has switched from a four-layer to a two-layer board. This last change means that the Eagle files for the Arduino Nano will now open with the freeware version of Eagle, making it easier to understand how the board is assembled and to create variations of it.
