🔧 Mega R3 Board by ELEGOO - ATmega 2560 + USB Cable - Ideal for Arduino IDE Projects - RoHS Compliant Review

At first I thought it was a bug in my code, but after testing several different Mega2560 boards with the same code I found that the voltage regulator in that block was defective. With a 5V supply with the USB off, everything works fine, but when using the 12V power connection on the plug, the voltage regulator overheats and the board starts to work erratically, randomly shutting down and restarting. - EDIT - After contacting the manufacturer and offering to replace the circuit board, it turns…

Arrived in 2 days, works great so far. I've literally only been playing with this for about an hour, but I'm wondering why I waited so long. I've been using the Raspberry Pi for a few projects for a long time, but recently I've wanted to see what Arduino has to offer. I downloaded the developer tool from the official website, plugged my new Arduino Mega 2560 into a USB port and within a minute I was already loaded with the Sketch code examples. I've since got the sound player and servo working.

I bought three. First I gave one star. Elegoo sent me three more boards at their own expense. I first had the same problem while downloading the AVRDUDE program. Then I noticed the same phenomenon with older boards that I had previously used for months with no problems. The Arduino IDE is open source and free, but is constantly updated and some versions have their own quarks. I've found these Elegoo boards to work great when doing the same thing I had to do to get my famous boards to accept the

Elegoo's version of the Arduino MEGA2560 R3 is so cheap you might be tempted to never buy an Uno type board again, at least for prototyping purposes. Also, unlike most "copies" (not really, it's open source hardware after all), Elegoo has actually provided some quality control and innovation in this area. The components are well soldered, the board is a nice black color, it has a real crystal oscillator and a 16U2 USB serial interface, there is a CE logo on the box and best of all, the pin…

After about 4 hours of shooting I decided everything was fired. Ordered one from keyestudio for a few bucks less and it worked with no issues. A lot of people say this is a great board. My review is definitely an exception. When I think about wasting 4 hours trying to get a buggy $13 board to work, that's just a huge loss! The following must be observed. without trying to mislead anyone. The symptom of the broken board was that I had no TX data, only RX, the switch. Troubleshooting led me to…

This is my second board from Elegoo. The first came with the kit and worked fine but its connectors have been trained so I don't think it will work for long. This would be the case with any brand of MEGA 2560. Anyway, I ordered this "new" from Revain. The one I received has been redesigned and has solder on top of the large Atmel chip as well as a small tangle of hair that I removed. After thinking about it I realized that I didn't need this board as I should know that it is reliable as it is…

This is a very very good clone compared to some other Mega 2560 clones I've bought on Ebay. It has a real crystal oscillator for the master clock, as well as EN-RESET tracing and a real ATmega16U2 for the USB<>serial interface. This last point is important if your project requires the Arduino to appear as a different type of USB device. In addition, 16U2 can be flashed separately from the ATmega itself. The 16U2 chip is supported directly by the Arduino, eliminating the need for…

I like this "thing". I can't believe how easy it is to get them working. For the price I paid it's a no brainer. What is $11 or $12 versus $45? I'll buy a couple of these to have on hand in case I break 1 or 2. It fitted right away, worked great, just ran the examples, didn't check all the outputs, but everything I tested worked fine. I haven't figured out what I'm going to do with it yet, but with all the excitement that comes with these things, I figured I should have it. I had a completely…

I'm an EE pensioner. I spend a lot of time keeping my brain working by doing small electronic projects. I've spent dozens of hours trying to get the PIC project to work - all to no avail. All examples I used were Arduino based; and I just couldn't decipher the Arduino code enough to understand the details. So I broke down and bought it hoping that if I could get it to work I would have enough electronic gear to reverse engineer the signals, if not the code. It worked. But this review is about…
