ELEGOO Mega 2560 R3 Project Starter Kit for Arduino Mega2560 UNO R3 Mega328 Nano - Including 16 Tutorials CD

Buen producto

This is an excellent little kit and the price is great. Nice variety of parts and the tutorial contained on the CD is a pleasant bonus. I have purchased from ELEGOO before and they are a great company to deal with.

I haven't delved too far into this kit yet, but it the quality and quantity of pieces is really good for the price. Any kid wanting to get started off in robotics/programming/general electronics would be well served by this Mega. It's not as versatile as the Raspberry, but for a learner this one is plenty of board.

The core of the system, the Mega 2560 R3 board, seems reasonable quality. The power supply board, for the breadboard, also appears to be of basically good quality.The breadboard has inconsistent pin socket performance. Most of the sockets are tight fit. The power/ground sockets fit noticeably looser. Not sure if this is normal (to accommodate thicker gauge power/ground?), but I have another breadboard that doesn't have this difference. In some cases it's difficult to put a lead straight in.The jumper wire ends are not reliable. In my initial project assembly, in two instances, when I pulled the jumper from the breadboard, the pin pulled out of the wire and stuck in the breadboard. On the flip side, the tips of the jumper wires are too fine a gauge and fit sloppily in the power and ground sockets in the breadboard but seem to fit snugly enough in the other sockets (maybe this is an issue more with the breadboard). For power and ground, you have to be careful because they can fall out easily. I purchased a separate, additional breadboard that does not have this issue, so this is mostly due to the breadboard included with the kit.The Mega2560 board is well equipped and overall a solid little platform. The pin sockets are all nicely labeled. However, they are a little quirky in that sometimes when inserting a jumper it feels loose, but it sometimes will be a little more snug. The socket insert seems a little off. I don't know if this is typical of the Arduino and its clones or these particular pin socket header sizes.In summary, you get a pretty good and fun starter kit for the money. And with all the I/O ports, the Mega 2560 is very versatile. I've been having fun putting some circuits together. For serious projects, though, I would recommend separately purchasing higher quality jumper wires and breadboard. I'm glad I didn't buy the bigger kit, but the pieces in this kit should continue to be fun to play with when I get around to it. I've already purchased higher quality jumper wires and breadboard. I am concerned about the quality of the I/O pin sockets on the board, though, but time will tell.I will say that the ADC on this device works very well and is fairly accurate. That's unlike the ESP32, which I've also tried. The ADC on that device has known linearity and range issues which require calibration and fussing if you want some accuracy within 0.2v and about 3.0v or so.The USB cable for power is quite short (about 18 inches). It's fine if you can keep the board close. I've been using a longer USB cable that I bought since I needed the board to be further from the computer.This is my first Arduino, so overall I am still happy I bought it. I've done a bit of research and Elegoo seems to be one of the better Arduino clones. They provide a bunch of datasheets and some documentation. Double check the data sheets. The one provided for the seven segment display is incorrect. The datasheet provided for the 74HC595 says "Philips" on it, but the component provided is not made by Philips. You can find many datasheets online to supplement your needs.

The wires that come with the kit are significantly easier to use than wires cut from a spool, as is with most breadboard kits I've used. The addition of organized resistors is also very nice as it saves time looking for resistors
