Best "cheap" Arduino Uno clone I've found so far.
by Robster2443 (5 out of 5 stars)

There's plenty of other, more in-depth reviews, so I'm just gonna hit a couple highlights:

This version has the 16U2 interface chip. You don't have to track down and install sketchy CH340 drivers. It looks like a genuine UNO to the programming environment.

It has the removable "DIP" package 328 processor. You may not need it, but it makes it possible to program your own chips and install them elsewhere ... or you can replace it if you fry the processor.

The headers have the pin assignments printed on the outside, as well as on the board. Same as a genuine UNO, and very handy.

They just work. Unlike some of the ultra cheap boards with 50% success rate I've bought and regretted. And they don't try to pass these off as "Genuine" like some of them do. I feel that these are the best option if you are buying a clone.

Works good but note some differences

Clearly this is an open source copy of the UNO board not made by Arduino - nor do they claim to be. That said, it seems to work very well and considering the price difference it is worth buying. Recently I had purchased a real Arduino that I built into a project on a permanent basis so I needed another one to experiment with. Couple of differences between the two that I noted. The real Arduino came with a plastic mounting base that insulates the bottom of the Arduino UNO from any sort of metal project box you might decide to use. Except for that you would have to find another way to insulate the board from the metal - plastic standoffs for example. The other curious difference was that the Elegoo comes with a short USB cable but the Arduino does not. Turns out that the short USB is needed for the Elegoo and will not work with the Arduino. Conversely the Arduino requires a standard USB (printer) cable, but will not work with the Elegoo short cable. That was my experience anyway and I tried it both ways several times. Honestly I found the plastic mounting base to be a more useful accessory assuming the Elegoo would work with a standard cable - which it did not in my case.

Highest quality of boards! Side pinout labeled view. The best ive used in the Arduino world !

Board Info

BN: Arduino/Genuino Uno

Uploaded sketches and tested basics. Looks and feels higher quality than other Arduino brands. You can tell they are doing a great job on designs. Everything is labeled perfectly and packaged like professionals. Double anti statics bag protection and sturdy box.

If you are looking for high quality and a very fair price then Elegoo has very good deals to make electronic design available for the world without sacrificing quality or cutting corners.

My wife asked today if I had a favorite brand to buy electronics from and this is the best quality for the best price around. I've tried other kits. Won't name them all like SunF.. and they just lack quality.

This is definately what your looking for if new or starting to learn Arduino. The design and side labels of pins make it very efficient to prototype on.

Nice UNO R3 Board
by Suji (4 out of 5 stars)

Elegoo UNO R3 Board ATmega328P board came nicely packed without any damage.

This UNO R3 board is well made and solder connections are very nice.This Uno R3 board is great prototyping tool for electronic project and this board has got 14 digital input/output pins, 6 analog inputs, USB connection, a power jack, reset button etc. This microcontroller can be used by connecting it to a computer with a USB cable or power it with an AC to DC adapter. Also, it comes with the USB cable. I tested this UNO board with existing Arduino sketches and they worked.

Well executed knock-off.

Works just like my authentic Arduino, for my uses I haven't seen any difference in performance. I am not using it with any shields or other add-ons, just the main board. Very happy with the purchase.

Inexpensive, works great.

Great little Arduino knockoff. Apparently it comes preloaded with the Blink sketch because the onboard LED wired to pin 13 was blinking when I plugged it in.

Pins are printed on the headers, which is a nice touch.

Also comes with a snazzy USB cable. I immediately went out and bought two more as stocking stuffers for young nerdlings in the family. I don't think you can go wrong at this price.

This component works as a cheaper alternative to the Arduino with no sacrifice made to its performance. Currently using for some electronics projects and would recommend.

Super Cool and Super inexpensive.

Had a chance to use it over the weekend. I own the RP-Zero, RP-3. I had never used an Arduino, and decided to try one, so I ended up buying this one for its price considering Arduino is open source and this is a clone of the UNO R3 specs.
I haven't had any issues yet, and have had no problem programming it with the Arduino IDE. The default COM port seems different than what the Arduino uses, but it's no big deal once you make the appropriate change in the IDE.

I love it!

Great little board to learn programming on!

I Bought this, with a relay board, for my first Arduino project. I wanted to try my hand at some some Lionel Train automation.

I come from a QuickBasic background and I've tried to lean C/C++ on and of for 20-some odd years and always gave up because my ideas were larger than my skill level.

This little board was just what I needed to give it another go. Because my project was limited to a few digital inputs and outputs it allowed me to learn the concepts of programming in C without my first projects growing way out of hand. A one-hour Youtube video, and the Arduino reference in-hand and I now have some fairly complex sequences that I could not have done without a microcontroller. The best part is I'm nearly done polishing the code and it's only day 3! This is a great way to learn fundamentals quickly. I'm going to have to get a few more of these. I'm hooked!

For mounting, I just cut a wood base to be screwed under the layout and hot-glued the PCB's to it. Works like a charm!

Review for the ELEGOO's Arduino Uno R3. I purchased a previous ELEGOO Arduino "Kit" which came with a bunch of other stuff. The Arduino worked just like the real thing. Purchased this second one as a spare or multiple projects going on at the same time. Showed up as a different COM port then the first one, which was cool. Easier to keep straight (for me). The chip was pretty tight in the socket (which it should be), but for me, I am building from scratch after prototyping and rather than go through the header design, I would just pull this chip and drop in the blank chips I got online, program the boot-loader, load up the new code, then swap it back out. Works great.
