UNO R3 Board ATmega328P with USB Cable(Arduino-Compatible) for Arduino

These are a great and inexpensive option for the arduino platform. These are easy to use. There are a ton of tutorials out there that will get you started right away. I use these to prototype as well as make complete projects. They have always performed well. I do not often do projects that use most or all of the pins, usually I use about half of them and have never had an issue with the board.

Five Stars This Arduino clone board worked perfectly for me right out of the box. No drama, no issues, no system software updates. Just upload the newest compatible version of Arduino with your OS. I am a reasonably experienced multi-platform computer user, but Mac is my preferred platform. For me, running Mac 10.13.6 High Sierra on a 2012 Mac Mini, Arduino 1.8.19 works flawlessly. AccelStepper, ezButton, and all the other popular libraries worked first time. The supplied USB cable was too short for my purposes, so I had to substitute a known working data plus power USB cable. Also, the device does not like being ported through hubs, though with the right hub it probably works fine. I just didn't bother. I did get one "device drawing too much USB current" alert from my Mac OS, but I have no idea why. It was just sitting there. I think it was a fluke or a momentary short or something as I had the board laid out on my desktop. Other than that, works like a charm. Accepts the XikenTec HCDC Shield. Not all clones are created equal. See my review of "another brand" of Uno clone, the very cheapest one currently on Amazon. I'm ordering another one of these Elegoo right now to replace that one, which I am sending back. The Elegoo branded Uno clone seems like a good compromise between clone pricing and OEM compatibility. Or, screw around loading drivers and fiddling with your OS for a day or two and save an additional five dollars. :-)

Works as expected for my dust collector project

Great board for learning the ins and outs of programming an Arduino. Easy to use. Great as a starter board. At this point I only use it for testing. For making actual projects I go with a much smaller and compact board like the ESP32 or even a Raspi Pico W. My gripes with it is its limited memory, no built in WiFi and the use of a USB B port. But as a starter board this is pretty great and documentation can easily be found online, even through youtube tutorials. As for the gripes thats really only gripes for the more professional user. Memory issues wont really be a problem for a starter. You dont really need WiFi to start learning it or i think its preferable to not have WiFi so people can stick to learning just the basic stuff first. Once they feel they need to tackle WiFi they can either upgrade to a different PLC or buy the seperate WiFi hardware. But perhaps beginners should learn to walk before they can learn to fly meaning they shouldn't tackle the wifi part before learning the basic stuff first. As for the USB B port. THat is old technology that really should only be used for printers and bigger hardware. Not something small like a PLC. The upside to it is that it makes the device stronger and less likely to break unlike usb micro and usb C which are easier to snap off during an accident.

I had bought this ELEGOO UNO R3 board to perform an update in my 3D printers, I had updated them from the factory firmware to the latest Marlin firmware and this little board performed great! As an original Arduino Uno board, I think this board is maybe exactly as an Arduino Uno at least I can't see any difference in compatibility and performance, so if you're looking for an Arduino Uno and you find this one, buy it with confidence because it will be basically the same thing, it comes with the cable, the cable is a bit short, but keep in mind that this cable is a bit hard to find sometimes when you need it, it is not common to have it at home unless you have a printer, because is the same type of cable that your printer uses. Oh! and it is tiny too, you can fit this board anywhere, it doesn't take much space, please refer to the measurements provided by the manufacturer but overall it seems to be the same size of an Arduino Uno.

This is a great board. It works identically to my old Arduino UNO. I noticed an extra blob of solder on my board but it doesn’t seem to create any short circuits and even if it did, I can use my soldering station to remove it. I can see how this would be a problem for those who aren’t into soldering but for me, being able to achieve the same functionality as the Arduino UNO for cheaper is worth it. I’d buy this again.

Just learning to code so this was my first experience with such an item. I went through the tutorials and feel pretty confident now. I even ordered some parts to create a personalized device. Lots of support, ideas and instructions out there to help you through. Wish I had started tinkering with this decades ago. This would be a GREAT idea for a teenager who is interested in electronics. By the way, it works perfectly and the price is very affordable. Get a beginner kit so you have the extra parts and pieces to experiment with. Hours of enjoyment and education fun!

While not the official Arduino, I have several of the Elegoo branded boards and have always had good luck with them. The first Elegoo unit I purchased was because the actual Arduino I originally wanted was not in stock, so I chose this brand instead of waiting for them to restock. I use them for model railroading and Christmas lighting, among a variety of other around the home projects. These boards are pretty much identical to the official Arduino in form and function and you can use code written for the Arduino interchangeably with this board. I have yet to encounter any compatibility issues, with some boards I own in use already for a number of years. I think it is a pretty good value for the money seeing as they go for about half of what the official product sells for.

Fungerade precis som jag hade förväntat mig, bra produkt

Llego rápido, descripción coincide con lo entregado. Buena calidad.

It work as stated

Had no issues with this board seems great !!!! Good documentation on the Elegoo site and works well with the arduino IDE.

This ELEGOO UNO R3 board is a fantastic choice for anyone getting started with Arduino or looking for a reliable board for more advanced projects. It's a great value for the price and offers everything you need to get started with electronics and programming. Here's what I like: Arduino-Compatible: This board is fully compatible with the Arduino IDE, which makes it easy to get started with coding and using the vast library of available projects and tutorials. USB Cable Included: The included USB cable is a nice touch and makes it easy to connect the board to your computer for programming and uploading sketches. ATmega328P Microcontroller: The ATmega328P is a powerful and versatile microcontroller that can handle a wide range of tasks. Digital and Analog Pins: The board has a good number of digital and analog input/output pins, providing flexibility for your projects. Good Quality: The board feels well-made and durable, which is important for electronics projects. Things to consider: Basic Functionality: This board is a good starting point but doesn't include any additional sensors or components. You'll need to purchase those separately for more complex projects. Overall, I highly recommend this ELEGOO UNO R3 board for anyone interested in Arduino. It's a great value, easy to use, and provides a solid foundation for your electronics and programming journey!
