It is very good quality and value for the money it is about the size of a credit card and is fun to work with

I bought this and a motor controller for sim racing rig. SimHub was able to connect and install without any issues.

The media could not be loaded. It hooks up to a 5v led strip but it has trouble keeping up with simple code. It is very inconsistent and even when I try having it only light up one led it still freaks out sometimes. I'm not sure what the other reviews have tested with this microcontroller but it is not suitable for my needs. Especially since it can't run properly. The only upside is that it would run the code and get it correct sometimes after a few attempts of running the same loop. But it's very inconsistent and only works 10-60 percent of the time. Although it could be because I have a bad circuit design. I doubt it because the board sometimes needs to be unplugged since it comes up with an error when uploading occassionally. It's okay for the price I guess. I would not use this as a main microcontroller. But if you're budgeted and need to see if something works it could be something to purchase for temporary use. It's performance is bad.

This is a good clone of the UNO R3. I have ordered Chinese UNOs before, and found that I could not use them immediately with the standard Arduino IDE. (The manufacturer wanted me to first run some piece of their software on my computer, which would somehow "fix" my installation to work with the clone board. (Note, this was not just a simple driver installation.) No thanks.)So, I was happy to see that this board worked right out of the box, with my existing IDE, after selecting "Arduino Uno" as the board. Simple scripts run as expected.The listing says voltage supply is 7-12V, but like an authentic Uno, this is for the jack. You can also power it with 5V through the USB port, as expected.

I couldn't figure out what was wrong with a scrolling text sketch I knew was working last year on a different board. I used a Nano last time. This board has trouble connecting to the Arduino IDE, when it does the Upload constantly sends back error messages, and the scrolling text displays completely wrong, if at all.I swapped out this board for another one I bought from Keyestudio and everything was fixed. The connection was instant, and scrolling text is perfect. So obviously this noname generic board is crap.DON'T WASTE YOUR MONEY ON THIS BOARD.

these are cheap and about 1 in 4 don't seem to work. I bought about 40 of these for use in a classroom and of the 20 I've opened, I have at least 5 that won't upload so I'll have to probably buy some other brand after checking them all. Some of them aren't returnable after students soldered parts to them(the soldering didn't make them fail) and it's so complicated to return anything to a school order, its not worth my time. So in the end, I tried to save money going with the cheap board, but wasted time with non-working boards and by the time it's done, I'll have wasted both time and money. Buy a better board.

This is a solid Arduino Uno Clone microcontroller. Works well and fully compatible with the Arduino IDE. Typically, I like to prototype with the Uno boards then scale down with other variants in the Arduino family. This board is perfect for that! The only thing that I wish it had, that I have on other boards is pin markings on the sides of the pin headers; which makes it easier to identify the I/O pins. However, it was not described or illustrated to have that feature, so I can't be mad at it!All-in-all, a good quality board to add to your Arduino lineup; you can never have enough microcontrollers!

I tried to upload a script to it using the Arduino IDE. It failed part way through each time. I tried different COM ports, different drivers, different computers and no matter what I couldn't get it to work. I wasted 3-4 hours trying to troubleshoot it. I saw another reviewers suggestion about using theKEYESTUDIO UNO R3 board and tried it. Everything worked first try with no fuss. And it is the same price. I'm definitely annoyed that I wasted so much time on this board trying to get it to work. I'm returning it tomorrow.EDIT: Changed my review from 1 star to 2 stars after seller reached out and offered a free replacement. Seems like the product has good customer service at least.
