ELEGOO MEGA R3 Board ATmega 2560 + USB Cable Compatible with Arduino IDE Projects RoHS Compliant
Key features
- •The Mega is 100% compatible with Arduino IDE and most shields designed for the Arduino mega2560 r3，RoHS Compliant
- •The chip is Atmega2560-16au and Atmega16u2, same with the official version.
- •Improved and expert version: 1. 0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Due that operate with 3. 3V. The second one is a not connected pin, that is reserved for future purposes.
- •Stronger RESET circuit. Use 5. 5 * 2. 1mm DC barrel jack (compatible with 5. 5 * 2. 5mm DC barrel jack)
- •It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.

A picture is worth a 1000 words - see attached pictures

This board works well but in looking at the silk screen printing on the headers/connectors I had to chuckle at the misprinted information provided. It would be better for your AD's and sales if you can correct this mistake for future builds of this board see attached pictures
Not sure if you will be able to see it but one picture has the word Digital as LATIGID and the other picture show the symbol for the UNO board PWM pins and not all pins 2 -12 that are PWM pins on the Mega2560 board.

One of the downsides to the Chinese clones is the CH340 USB comm chip. You have to get the drivers on the internet. The "real" Arduinos use FTDI chips which cost more but have native drivers on most OSs. I bought this because it was cheap, I know where to get the drivers and if the thing fails early I can buy another one and still save money.
Compatible with Arduino shields
Amazon Customer jhb✓ Verified Purchase•November 8, 2017
No design hiccup as discussed in another review (header spacing). So far this unit appears plug compatible with the Arduino Mega. It is a nice touch that they include the USB cable. Also, the headers are silk screened on the sides which is helpful. The issue about incorrect spacing in another review is not a flaw, it is keeping the design identical to the original Uno and subsequently, the Mega header spacing. Arduino shields mate up just fine. The attached photo shows an Adafruit LCD shield mated up to the Elegoo.
Received a faulty board, but was promptly replaced.

At first I thought it was a bug in my code, but after testing a few different Mega2560 boards with the same code, I discovered that there is a flaw with the voltage regulator in this unit.
At 5v powered off USB, it works just fine, but using a 12v power connector on the barrel plug, the voltage regulator overheats and the board begins acting erratically, randomly powering off and rebooting.
--EDIT--
After the manufacturer reached out and offered to replace the board, it turns out that I had a faulty unit and the replacement is working as expected. Changed my review to reflect this: Occasionally things make it past QC, but how the manufacturer handles the situation is just as important as the product itself, and they took care of it promptly.

Elegoo made good on the problems I had with the first three boards I bought from them. They are fine boards.

I bought three. At first I gave it one star. Elegoo sent me three more boards at their own expense. At first they gave me the same problem
with the AVRDUDE program download. Then I noticed this same phenomena happening on old boards I had been using for months without
any problems before.
Arduino IDE is open source and free but it is constantly updated and some version have their own quarks.
I found that these Elegoo boards work just fine if I do the same thing I had to do to get my known boards to accept a download.
Even though "port" setting under the "tools" menu says the board is attached to a COM port click on it anyway.
For some strange reason this fixes the problem and without changing anything else the program downloads and the board performs
as it should. I think the original problem that caused me send the boards back for a refund was an Arduino IDE problem.
