Welcome the Arduino Zero, jointly developed by Atmel and Arduino, and targeted at "the next generation of IoT development". It's described as "a 32-bit extension" of the Arduino Uno - which is also 32-bit, note - and basically offers higher performance for the open-source hardware platform.
The Arduino team writes:
The Zero board aims to provide creative individuals with the potential to realize truly innovative ideas for smart IoT devices, wearable technology, high-tech automation, robotics and projects not yet imagined.
The first prototypes of Arduino Zero will be on display at the Maker Faire Bay Area 2014 in San Mateo, USA, on May 17 and 18.
In terms of its hardware spec, the Zero board features the Atmel SAMD21 Microcontroller (based on a 32-bit ARM Cortex M0+ core), 256KB of flash and 32KB SRAM memory in a TQFP package, it's compatible with the 3.3V Shield that conforms to the Arduino R3 Layout, and Atmel’s Embedded Debugger (EDBG) to ease software debugging.
"The Zero board expands the Arduino family by providing increased performance to fuel the creativity of the maker community," says Massimo Banzi, Arduino co-founder and CEO.
"The flexible feature set enables endless project opportunities for devices and acts as a great educational tool for learning about 32-bit application development."
