arduino.org released another arduino board - Arduino M0. Arduino M0 is based on 32 bit ARM Cortex? M0, SAMD21 MCU in 48 LQFP package.
Operating Voltage: 3.3V
Input Voltage (recommended): 6-15 V
Input Voltage (limits): 4.5-20 V
Digital I/O Pins: 20, with 12 PWM and UART
Analog Input Pins: 6, 12-bit ADC channels
Analog Output Pins: 1, 10-bit DAC
DC Current per I/O Pin: 7 mA
Flash Memory: 256 KB (z toho 4KB pro bootloader)
SRAM: 32 KB
Clock Speed: 48 MHz
Arduino M0 can be supplied from USB or through external power supply.
The board can be loaded from Arduino IDE.
Arduino M0 Pro includes another microcontroller for debugging - Atmel?s Embedded Debugger (EDBG)
