Warning: Unlike most Arduino boards, the Zero runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Applying voltages higher than 3.3V to any I/O pin could damage the board.
The Arduino Zero Original is a powerful yet simple 32-bit microcontroller board, expanding the capabilities of the Arduino family beyond the UNO. Powered by the Atmel SAMD21 MCU with an ARM Cortex-M0+ core, the Zero is perfect for developing next-generation projects in IoT, robotics, wearables, and high-tech automation. One of its standout features is the Atmel Embedded Debugger (EDBG), which provides a complete debug interface and virtual COM port without additional hardware—making programming and debugging seamless. With 20 digital I/O pins, 12-bit ADC, 10-bit DAC, PWM support, and multiple serial interfaces, the Zero offers great flexibility for developers. Running at 3.3V logic, it is compatible with shields that support this voltage level. Compact, lightweight, and versatile, the Arduino Zero is an excellent educational tool as well as a robust development platform for advanced embedded applicatio Featured By RoboticsBD.

Arduino boards based on AVR microcontrollers get a reset and restart sketch execution each time the Serial Monitor of the Arduino Software (IDE) is opened. This is also the mechanism used to upload sketches to these boards. This board is different: when the Zero is connected through the Programming Port and you open the Serial Monitor, the board does not automatically reset and the sketch loaded keeps running. To restart the sketch you need to press the reset button on the board itself.
