Already using it as the basis of a 3D scanner based on an IR laser diode. (The resolution of the VL6180 sensor leaves a LOT to be desired, but the Arduinoid UNO R3 is as good as any.) I was concerned about the USB protocol being provided by an ic different than the one on the original, but what's there works just fine. I bought a wall wart which does seem to power it up, but possibly not enough to run the LCD daughterboard properly. Works fine with the USB power, and I'll keep trying other DC power sources.

easy to use, bootloader is fast, the micro usb power supply easier to use. Many projects to work on, a good value.

This UNO works fine with the Arduino IDE. No modifications are needed, it works right out of the bag. The board looks well constructed and seems to work like a regular UNO. I originally bought this because I thought it had a mini USB connector like the NANO. It has a micro USB connector like an Android cell phone. I do not like micro USB connectors because they do not hold up over time. The supplied USB cable works well, but is only 2 foot long. I am happy with this board for the price, but in hind sight I would have purchased the regular UNO with the printer style USB connector, since it is much more rugged. If I were mass producing a project, rather than debugging, the USB connector wouldn't be an issue.

We ordered this for teaching purposes and it worked out well. Also we got the items delivered earlier than we expected since we wanted to have them before a specific date. The only issue was there was no support for this item so we made plastic bases with three holes taped for standoffs. Then we used plastic screws to fix the board on the standoffs. There were four holes on the board but three were enough to keep it above the plastic base.

At first it crashed in Arduino IDE, but once I downloaded and installed the new driver from wch.cn, it worked perfectly. I created my first project at circuito.io using a depth sensor and some LED's and it works just fine.
