The Zero is compatible with all the shields that work at 3.3V and are compliant with the 1.0 Arduino pinout. The board contains everything needed to support the microcontroller simply connect it to a computer with a micro-USB cable or power it with a AC-to-DC adapter or battery to get started. Applying voltages higher than 3.3V to any I/O pin could damage the board. The maximum voltage that the I/O pins can tolerate is 3.3V. Warning: Unlike most Arduino boards, the Zero runs at 3.3V.
EDBG also supports a virtual COM port that can be used for device and bootloader programming. 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. The board is powered by Atmel’s SAMD21 MCU, which features a 32-bitĪRM® Cortex® M0+ core.
The Zero applications span from smart IoT devices, wearable technology, high-tech automation, to crazy robotics. The Zero board expands the family by providing increased performance, enabling a variety of project opportunities for devices, and acts as a great educational tool for learning about 32-bit application development. The Zero is a simple and powerful 32-bit extension of the platform established by the UNO.
