Arduino Zero

Arduino Zero

The Arduino Zero is the next step in the Arduino Uno's evolution. It adds a 48MHz ARM Cortex M0+ core, with embedded debugger. The memory capacity is 256kB Flash and 32kB RAM. Like the Due, the board operates at 3.3V only, so be careful what you connect to it. There are separate USB programming and standard USB serial ports.

PWM is available on all digital pins except 0, 1, 2, and 7. In addition, it has a real 10-bit DAC for an analog output. The pinout of the board is identical to the Uno, but a significant change is that A0 doubles as the DAC output.
