I love these arduino MCU as they are reliable and fun to program for my Model Railroad.

If you are wondering if this is a Genuine Arduino. It is not, but it works just fine. I use many of these on my model railroad and even used one for the control on a professional PCB test fixture. I have bought over 10 of these and every one was good. The USB interface is sometimes an issue with "non-genuine" Arduidos, but this one. It uses an Atmel chip and I have had zero issues with the USB. I have used it on both PC and Apple. The quality of the soldering and PCB is "Good enough", again every one I have bought works. I have fried a few of them but these were my mistake, not a quality problem from Elegoo. I also bought the starter kit from Elegoo. The hardware in their kit is fine but the documentation has some mistakes. I am an EE and figured out the problems, but for a true beginner you want a better instruction manual. For the money these are a good value and get the job done.

I am a retired EE. I spend a lot of time keeping my brain working by doing little electronic projects. I had spent several dozen hours trying to get a PIC project working - all to no avail. The examples I was using were all Arduino based; and I simply couldn't untangle the Arduino code enough to understand the details. So I broke down and bought this in the hopes that if I got it to work I had enough electronic equipment to reverse engineer the signals if not the code. It Worked. But this review is about the Elegoo Mega. I have only done two things with the platform. But I can tell you that both projects worked fine as though I had a "real" Arduino... of course the Arduino stuff is all open source, so maybe I should not be surprised - but it was nice to not have to worry about any compatibility issues as I was learning. I will continue building projects in the PIC Ecosystem... I get to fully understand the inner workings of the code - all of the code. But since the Arduino Ecosystem is so much more vast than any other platform, I am sure that I will continue to use this little board to get a handle on how to jump to another platform... and I don't feel like a traitor to Mcirochip since the AVR products are part of the same company now. If you are worried about build quality or compatibility, based on my very limited experience (the project I was working on touched a lot of the Arduino Ecosystem - so I might not have a "lot" of project experience I number of projects - but I have quite a lot of experience with the Arduino Ecosystem anyway) worry not. This product is very nice indeed...

I got my 3D printer from Elegoo a while back. They had barely released it, coincidentally about the same time I entered the market for one. It was so easy to use and setup! My experience with this product changed my opinion of Elegoo from a neutral "ok, it's just another company" to "this place makes some really good stuff." Fast forward to now: I purchase this board, assuming that it was good because it was Elegoo. It arrived quickly, but I didn't use it until a while later. When I did try to use it, it wasn't working! Very disappointing, but also very unusual for Elegoo. I then go to contact Elegoo support for help and they sent me a replacement with next-day shipping! Although the shipping speed might be on Amazon's part, Elegoo still had amazing customer service! If you're looking for a board for any project, Elegoo is the way to go! This board provides amazing value for its cost; I can say with confidence that I will be purchasing a lot of these in the future!

This Arduino Mega 2560 R3 clone has proven to be perfectly reliable over the past month. Even when I accidentally shorted a pin directly to ground (and burnt out a port on my USB hub), this guy kept on ticking, with no damage. (Although, admittedly, it would have been nice if its polyfuse had acted faster then, but I can't really fault it. Complete user error.) It seems to be fully compatible with the real Mega 2560 R3, and it required no special drivers for Windows. It worked out of the box with the stock Arduino software. The black soldermask PCB is a nice touch. I also bought their blue version ( Elegoo MEGA 2560 R3 Board ATmega2560 ATMEGA16U2 + USB Cable Compatible With Arduino ) and both seem to work equally as well. Only difference is the color. The port names are silkscreened on the sides of the headers, which is great and something many other Arduino clones do not have. It is much easier reading the clear labels there than on the PCB itself, especially with lots of things connected. The headers aren't soldered PERFECTLY straight but I've rarely seen anyone get that right, and it was so slightly that it doesn't matter in practice. Only if you look close. There was no problem with any of my shields. Only potential complaint was that there were a few copper filaments kind of stick underneath one of the headers. I removed them with a tweezers before powering it on for the first time. They looked like they could have been a remnant from machining through a copper plane during PCB manufacturing(although not I'm sure why the copper planes would go all the way to the edge). Anyway, they were relatively easily removed and not worth deducting a star for. But maybe just give this a quick once-over before plugging it in. Overall, no regrets--especially at ~1/4 the cost of an authentic Mega 2560 R3! It even came with a USB cable (which I haven't used).

This is my second board from Elegoo. The first came in a kit and has worked fine but it's connectors got a workout so I don't trust it to work long term. This would be the case for any brand MEGA 2560. Anyway I ordered this "new" one from Amazon. The one I got was reworked and has solder flux on the top side of the large Atmel chip plus a little hair tangle about which I removed. After thinking about it, I have no use for this board since I have to know that the board is rock solid since it's going into a system that will hopefully run for many years. So, for me this board has been a big disappointment. An image is attached. At the top of the large Atmel chip you can see the traces change their reflection as they pass under the solder flux. Also some pins on the top of the chip are skewed just a bit. Update: Without my asking for a replacement, Elegoo sent me another board. I am changing my rating from 1 star to 4. This replacement board looks and works fine. I really like the labels they have on the side of the connectors showing the pin descriptors. And, since my development was on one of these boards, I have no problem putting it into the system.

Good quality product. Easy to program and operate.

Performs as expected and saved money

So good quality

I've used many Elegoo Arduino boards and they've never let me down. I trust Elegoo for their reliability, and it helps that they are competitively priced. Good stuff.

La verdad me asustaba un poco que el producto no llegase a funcionar con la plataforma de arduino o que estuviera hecho con mteriales de mala calidad, sin embargo me sorprendieron con la calidad del producto, llego antes del tiempo establecido y funciona de maravilla dentro de la plataforma.

Good affordable local source of arduino boards. Mega is overkill for my needs but the discount is too good

Fast shipping. The product was in good quality and as described.
