With the Arduino Leonardo, everyone's favorite hackable microcontroller turned a new page. Now it's time to bring that simplified design and slightly expanded feature set to the rest of the family, including the itty-bitty Arduino Micro. The tiny, embed-friendly board was designed with help from Adafruit Industries, one of the biggest players in the DIY market. At the heart of the Micro is the same 16MHz ATmega32u4 chip that powers the Leonardo, which means all the necessary USB controls are baked into the processor. Obviously, the layout here is different, so you wont be mounting the Micro to any shields, but with 20 digital I/O pins, 12 analog input channels and seven PWM channels, there's plenty of room for wiring up your own expansions. Amazingly it crams all that capability in a package just 48mm long and 18mm wide. The Arduino Micro will be available exclusively through Radio Shack and Adafruit first before becoming more widely available next month. The board is available with headers for €21 (roughly $27) and without headers for €18 (about $23). For more, check out the PR after the break.
Arduino announces the release of the new Arduino Micro board
Arduino announces the release of the new Arduino Micro board. Based on the technology behind the Leonardo board, its main feature is the very small size.
The Arduino Micro packs all of the power of the Arduino Leonardo in a 48mm x 18mm module (1.9″ x 0.7″).
It makes it easier for makers to embed the Arduino technology inside their projects by providing a small and convenient module that can be either used on a breadboard or soldered to a custom designed PCB.
The Micro has been developed in collaboration with Adafruit Industries, one of the leaders of the Maker movement. Adafruit is already developing a series of accessories for the new board that will complement its power and simplicity.
Throughout the month of November the product is available exclusively from Adafruit online and Radio Shack in retail stores.
Starting next week the board can pre-ordered from all Arduino distributors while shipments will start from November 26.
The Arduino Micro will be available in two versions:
A100053 Retail version with headers (MSRP): 21.00 EUR + Taxes
A000053 Retail version without headers (MSRP): 18.00 EUR + Taxes
Main features of Arduino Micro:
The Arduino Micro is a microcontroller board based on the ATmega32u4.
Like its brother the Leonardo board, the Arduino Micro has one microcontroller with built-in USB. Using the ATmega32U4 as its sole microcontroller allows it to be cheaper and simpler. Also, because the 32U4 is handling the USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more using the USB-HID protocol.
It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started.
This allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

Arduino, the first widespread Open Source Hardware platform, was launched in 2005 to simplify the process of electronic prototyping. It enables everyday people with little or no technical background to build interactive products.
The Arduino ecosystem is a combination of three different elements:
-A small electronic board manufactured in Italy that makes it easy and affordable to learn to program a microcontroller, a type of tiny computer found inside millions of everyday objects.
-A free software application used to program the board.
-A vibrant community, true expression of the enthusiasm powering the project. Every day on thewww.arduino.cc website thousands of people connect with other users, ask for help, engage and contribute to the project.
About Adafruit Industries
Adafruit was founded in 2005 by MIT engineer, Limor "Ladyada" Fried. Her goal was to create the best place online for learning electronics and making the best designed products for makers of all ages and skill levels. Since then Adafruit has grown to over 25 employees in the heart of NYC. Adafruit has expanded their offerings to include tools and equipment that Limor personally selects, tests and approves. Adafruit has one of the largest collections of free electronics tutorials, open-source hardware and software to help educate and inspire the next generation of scientists and engineers.
