ELEGOOUNO 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.

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!

Five StarsThis 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 perfectly

Works well with beginners and experienced hobbyists. I strongly suggest the book “coding Arduino by Simon Monk” because it provides a smooth tutorial for coding arduino unos and internet-compatible arduinos.

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.

Great little microcontroller for prototyping. If you don't already have a start kit then get one! This doesn't come with anything, just the board and a USB cable.

Excellent replacement for an older board that failed after five years of use.
