Arduino Zero
Arduino Zero is a simple and powerful 32-bit extension of the UN-established platform. This board aims to provide a platform for innovative projects in the areas of intelligent IoT devices, wearable technology, high-tech automation, crazy robotics and much more. The Zero is a simple and powerful 32-bit extension of the UN-created platform. The Zero-Board extends the family through increased performance, enables a variety of project possibilities for devices and serves as a great teaching tool for learning the development of 32-bit applications. Zero applications range from intelligent IoT devices, wearable technology, high-tech automation to crazy robotics. The board is powered by the SAMD21 MCU from Atmel, which has a 32-bit ARM Cortex M0+ Kern. One of the most important functions is Atmel's Embedded Debugger (EDBG), which provides a complete debug interface without additional hardware, thus significantly increasing the user-friendliness of software debugging. EDBG also supports a virtual COM port that can be used for device and boot loader programming. Caution! Unlike most Arduino and Genuine boards, the zero runs at 3.3 V. The maximum voltage that the I/O pins can tolerate is 3.3 V. The addition of 3.3 V to any I/O pin could damage the board. The board contains everything was needed to support the microcontroller; simply connect it to a computer with a micro USB cable or supply it with an AC/DC adapter or battery to get started. The Zero is compatible with all shields that operate at 3.3V and conform to Arduino pin assignment 1.0. This text is machine translated.

The only thing that gave it away was that the PC did not recognize the new USB device when I plugged it in.

This Arduino Zero arrived with a manufacturing defect. The Programming USB flakily and frequently drops the connection to the PC. The USB cables (which work well with 3 other Arduino Zeros) leads and solder pads on the board bottom ring out with excellent connectivity. When the PCBA is pressed on the top surface in the component-free space just above the Programming USB connector, the connection is solid and does not drop. Looks like a broken trace on an internal layer.

The Zero came pretty quick. I wanted it because of the built-in debugging feature.I had some trouble in bringing it to work. At the end, it turned out I needed to flash a bootloader or something like that. Now it works great.

I am testing...Good product as original Arduino
Great service - fast delivery. Nice Arduino ZERO --- works great.
The key thing is that the product works. After that, it shows up like two days after you order it.When you have programming problems, there is a ton of stuff in the blogs to get your through it. Both examples and people helping you.How can you go wrong?--jim
I bought this board because I had a Uno Wifi but ran out of program memory as soon as I added the WiFiNINA and SD card libraries. Since I had already purchased shields for the Uno, the Zero seemed to be a possible solution. Was able to get my Uno program running on the Zero pretty quickly. But I have a web user interface and a real-time data logger that really need thread support since I had to delay the UI while the data was being collected. I had no luck getting mbedOS, Zephyr or Simba working on this board. Got back from a business trip this week and the board is dead. It will download programs but the debugger will not work. The old uno still works with the IDE so it looks like a hardware problem.
Debugging without any additional hardware and the IDE 2.0 is great stuff. Therefore I bought this processor, tried it and it impressed me very much. I hope to get better progress with this stuff.
