Arduino Zero specifications:

  • Microcontroller – Atmel ATSAMD21G18 32-bit ARM Cortex M0+ MCU @ 48 MHz with 32 KB SRAM, 256 KB flash, up to 16KB EEPROM (By emulation). 48-pin LQFP package.
  • Digital I/O Pins – 14, with 12 PWM and UART
  • Analog Input Pins – 6, including 5 12bits ADC channels and one 10 bits DAC
  • DC Current per I/O Pin – 7 mA
  • USB – 2x micro USB ports
  • Debugging – USB via Atmel’s Embedded Debugger (EDBG) on-board debugger, and JTAG
  • Misc – reset button, 5 LEDs (Tx, Rx, L, On, Debug)
  • Operating Voltage – 3.3V

That’s about all we know for now, as tools support (Arduino IDE?), availability and pricing have not been announced. If you are at the Maker Faire Bay Area 2014 in San Mateo on May 17 and 18, you’ll be able to check out the board at Arduino (#204), Atmel (#205), and/or ARM (#405) booths.
