Arduino Ethernet Shield 2 [A000024]

No complaints. Works well, is made well, has a lot of tutorials, and is easily utilized

This was my first “shield” (what Arduino refers to its add-on boards). It worked just as expected. I was able to host a simple html webpage on my Arduino. Having just gotten into programming integrated circuits, I am pleased with how easy it was to use this. The pins all fit into my Uno without issue. The box came with informative material and was free of damage. The price point for this (and all Arduino accessories) can’t be beat.

Works well and is reliable when you code correctly. A little bit of a learning curve with quirks you might not expect so read as much about it as possible before giving up on it.

It works as expected. It is connected 24/7 and sending udp packets every second without issues or disconnections . Using the standard Ethernet library .I wish it was documented better . The documentation of the shield is poor almost no documentation about the colorful header on the board and no documentation how to use the power over lan feature. The board well made and looks high quality.

Received this shield and installed it on an Arduino Mega, I had to do quite a lot of web searching in order to figure out just what you could do with it, as there is very little support from Arduino. However, there are many hobbyists out there who came before me and I just copied some of their projects, added a few tweaks of my own, and managed to get this working. I created a micro-server that will load up a web page from the on-board SD card. Am presently working on a sketch that will allow a scrolling RSS feed to be displayed on a 16x2 LCD. All in all, a great shield, but for intermediate to advanced users. One important thing to keep in mind is that this shield works best using the Ethernet2 library. Make sure you install that first on your Arduino IDE to avoid problems.

Superior quality, for the price.

I supported arduino in my first ever attempt to use microcontrollers. I bought this uno r3 and also a WiFi rev2 and a starter kit. Much of my initial work and concept would not have been possible had I not found their site about connecting two arduino over tcp client server. So it’s only fair that I return the support. Thanks

Got it, played with it, and got it to work within my project. Coupled with an Arduino Mega, I decided to add a PoE module. The 5v version works fine, but the Mega has low voltage, so I ordered the 12v version. This board craps out after about a minute of having 12v applied to it, even though the Arduino.org web site specifically states it should be using the 12v module. Posting on the Arduino.org forums resulted in no help. Regardless, this is the best ethernet shield out there, hands down. Because it is a W5500, there's no fiddling with the high and low settings of certain pins to enable or disable SD card reader or ethernet like on any W5100.After a ton of research, and ordering more PoE modules, I have found that this board causes the Arduino to lock up when using any 12v PoE module. This thing has been working rock solid since figuring that out. I really can't say enough about this board. I wish it were cheaper, but even at this price it's worth every penny. PoE support, the plugs on top, the W5500 ethernet chip, the ability to write to SD while doing ethernet stuff, is key over a W5100 which is on the vast majority of ethernet shields out there.The other HUGE advantage of these boards are that they come with a MAC address. Cheap-o boards never do, so you have to make one up. These have one assigned, even though I've yet to find a way to read that MAC off of the board. What I do is create a script to write the MAC to the EEPROM, then read the MAC from the EEPROM on startup, then provide that to the Ethernet library.Today I received another one of these boards, and it is missing half the header for PoE. There's a quality control issue going on. See photo.Unfortunately, Arguino.org lacks support, so you really are on your own.
