In the next paragraphs you’ll find my experiences with three Arduino libraries. And then I’m not even mentioning the lack of good info to determine what pins are to be used, so I had to figure that out by myself. Since I randomly picked this particular model, I had to find out the hard way that things do not seem all that easy, since it’s not compatible with the Arduino “Ethernet” library that comes with your Arduino IDE. You can choose the top connectors or bottom pins (breadboard) while experimenting, but you could consider cutting off the bottom pins for your final product. Including the Arduino Nano (clone) the setup would be app 6.7 cm (~2.6″) long, 1.7 cm (~0.7″) wide, and 1.7 cm (~0.7″) tall – depending on how you use the pins at the bottom and how you mount your Nano of course. The module and Nano combined make this thing VERY compact. My main reasons to pick this one (besides being totally unaware, at the time, that this is not the same as the Arduino Ethernet shield) were: Price, came with a Nano and size. The connectors however are geared towards mounting an Arduino Nano of course. I found mine at eBay for $18 which came with an Arduino Nano (left in the picture – Nano not displayed), which works just fine with, for example, an Arduino Uno as well. Illustration below: Just two of many variations of the ENC28J60 modules. The only thing that can be tricky is finding the right pins for the right library.

When looking for one, you’ll find that there are numerous variations available, and they pretty much all work the same, just the board and pins look different for specific purposes.
