Reliable Microcontroller That Just Works Every Time
I used this Arduino Mega 2560 as the controller for my marble clock project, and it has performed flawlessly.These boards are incredibly reliable and, in my experience, they simply work every time. With a large number of digital and analog inputs, the Mega provides plenty of flexibility for more complex projects involving motors, sensors, and other components.The board is easy to program, well supported, and offers excellent value for the money. If you need a dependable microcontroller for a serious DIY or automation project, the Arduino Mega is an outstanding choice.Ver másVer menos

Great Arduino product
Direct from Arduino products have always worked on delivery. This Mega 2560 Rev3 did also. The library of functions for many accessories is also very good and well documented, which helps in programming new applications.

Genuine Arduino Mega 2560 Rev3
Good "old-school" 8-bit, 5-volt Atmel ATmega2560 microcontroller based development board. Includes a clear plastic base plate that prevents accidental short circuits and protect surfaces from scratches. Make sure you have a USB Type-B cable for programming (not included).Ver másVer menos

Solid, nice plastic base, genuine Arduino Mega2560
It's exactly what I expected, and it has provided a nice first foray into microcontrollers for this old hand at programming and electronics. It took only minutes to install the free IDE (integrated development environment -- the "programming" tool) and to run a test program on the board. So far I've used it to drive strips of several hundred WS2812b individually addressable programmable LEDs for combination functional/aesthetic lighting installations, and it takes input from either pushbuttons or touch sensors (using I2C bus). But essentially it was the quality I expected for the price I paid.That said...Having the included solid plastic base while prototyping and developing code is somehow a consistently underrated feature that this genuine Arduino Mega2560 board has. I can't stress the benefits of avoiding: accidentally shorting, lowering resistance to ground of, or adding capacitance accidentally to a pin because the underside of the board is touched when moved, or dust containing some metallic particles you didn't notice is on your desk. Point is, for all the functionality of this board, perhaps most impressive thing about the package was a single, undocumented, completely self-explanatory, highly useful simple accessory, simply because it isn't something most people have sitting around. Seriously, how often does an included accessory require no installation, do it's job perfectly, not need replacing, be able to be removed if unwanted, requires no explanation, and avoids both potentially board-destroying situations AND potential programming nightmares where anomalous input could be intermittently created. By including this feature, novice developers who are less likely to be actively aware of certain precautions are saved from a disturbingly short or horribly frustrating first experience working with microcontrollers.I also can't stress enough that if you use microcontrollers which make use of the Arduino IDE (which is MANY), it's a worth buying a slightly more expensive genuine Arduino product once and a while (if they fit your project) to support the company that provides the software and support for free to the world. No, I'm not affiliated in any way, just a fan of their business model.Ver más

Great little microcontroller
This is about the Arduino MEGA2560 R3. I already had the same but R2. Both are great. I haven't needed the extra pins of the R3 yet, but can see where they could come in handy. As far as I have seen, the MEGA2560 gives the best bang for the buck of any of the microcontrollers out there. The 256k of flash program memory is more than enough for some really big programs. The built-in USB port is very convenient for development work and also powers the Arduino board. As a retired EE/IT guy, my use now is strictly for hobby, so keeping costs down is important. So I also appreciate the built-in female headers for easy (and inexpensive) connections with external circuitry. So on the plus side are low cost, convenience, and a very generous programming space of 256k flash. The 4k of EEPROM is large enough for my present needs for semi-permanent storage of tables and things. After using the R2 and R3 for over a year now, my only negatives are from bumping into RAM limitations as there is only 4k of RAM for your variables, the stack, and the heap. And to compound the issue, the Arduino version of C++ does not implement dynamic memory allocation. It would be nice to either bump up the size of RAM or allow the programmer more ability to manage what RAM there is (or both). The compiler's use of the heap is the major issue as I have had it grow into the stack, with resultant disaster to the program. I have come up with workarounds, but life would be much easier with more RAM and/or dynamic memory allocation. Overall though, I still give it a five-star rating as a GREAT little mC.Ver másVer menos
