The Zero is a simple and powerful 32-bit extension of the platform established by the UNO. This board aims to provide a platform for innovative projects in smart IoT devices, wearable technology, high-tech automation, crazy robotics, and much more
the Zero applications span from smart IoT devices, wearable technology, high-tech automation, to crazy robotics. The board is powered by Atmel’s SAMD21 MCU, which features a 32-bit ARM Cortex® M0+ core. One of its most important features is Atmel’s Embedded Debugger (EDBG), which provides a full debug interface without the need for additional hardware, significantly increasing the ease-of-use for software debugging. EDBG also supports a virtual COM port that can be used for device and bootloader programming.
To keep your Zero's Bootloader up to date, the Update Procedure explains what you should do each time there is a new Core release.

- 32-bit core that allows operations on 4 byte wide data within a single CPU clock. (For more information see the int type page)
- CPU Clock at 48MHz
- 12 channels DMA controller that can relieve the CPU from doing memory intensive tasks
- 32 bit Real Time Counter (RTC) with clock/calendar function
- 32 bit CRC generator
- Two-channel Inter IC Sound (I2S) interface
- Peripheral Touch Controller (PTC)
- VIN. The input voltage to the board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or if supplying voltage via the power jack, access it through this pin.
- 5V. This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board if it is not sufficiently regulated. We don't advise it.
- 3.3V. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 800 mA. This regulator also provides power to the SAMD21 microcontroller.
- GND. Ground pins.
- IOREF. This pin on the board provides the voltage reference with which the microcontroller operates. A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs for working with the 5V or 3.3V.
- Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the Serial1 class. The native usb port instead responds to the SerialUSB class
- External Interrupts: available on all the pins except pin 4.
- DAC: A0. Provide a 10bit voltage output with the analogWrite() function.
- PWM: 3, 4, 5, 6, 8, 9, 10, 11, 12, 13. Provide 8-bit PWM output with the analogWrite() function.
- SPI: SS, MOSI, MISO, SCK. Located on the ICSP header only support SPI communication using the SPI library.
- LED: 13. There is a built-in LED driven by digital pin 13. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off.
- Analog Inputs. Six of the 20 general purpose I/O pins on the Zero provide analog input. These are labeled A0 through A5, and each provide up to 12bits of resolution (i.e. 4096 different values). By default they measure from ground to 3.3 volts, though is it possible to change the upper end of their range using the AREF pin and the analogReference() function.
- TWI: SDA pin and SCL pin. Support TWI communication using the Wire library
- AREF. Reference voltage for the analog inputs. Used with analogReference().
- Reset. Bring this line LOW to reset the microcontroller. Typically used to add a reset button to shields which block the one on the board.
- Programming port: To use this port, select "Arduino/Genuino Zero (Programming Port)" as your board in the Arduino IDE. Connect the Zero's programming port (the one closest to the DC power jack) to your computer. The programming port uses the EDBG as a USB-to-SWD chip.
- Native port: To use this port, select "Arduino/Genuino Zero (Native USB Port)" as your board in the Arduino IDE. The Native USB port is connected directly to the SAMD21. Connect the Zero's Native USB port (the one closest to the reset button) to your computer.
- Serial is a hardware serial port internally connected to the EDBG chip and corresponds to the virtual serial port on your computer when you connect the Arduino Zero through the programming USB connector;
- SerialUSB is a virtual USB serial port, which corresponds to the virtual serial port on your computer when you connect the Arduino Zero through the native USB connector.
- Serial1 is the hardware serial port connected to pin 0 and 1, which is free to use to connect to external serial devices.
