According to them, the Arduino Zero will be powered by Atmel’s SAMD21 MCU, featuring an ARM Cortex M0+ core and Atmel’s Embedded Debugger. This allows developers access to a full debug interface without the need for additional hardware, thus making it easier for those who are just starting out and don’t have the access or funds for additional pieces of hardware.
The Arduino Zero will also come with 256kb of flash and 32kb of SRAM in a TQFP package, making it compatible with 3.3V Shields as long as it conforms of an Arduino R3 layout. According to Massimo Banzi, Arduino’s 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.”
Arduino will be showcasing the first prototypes of the Arduino Zero at the Maker Faire Bay Area 2014 in San Mateo on the 17th and 18th of May, so if you’d like to learn more, you can pop on over if you are in the area to check it out.
