arduino ethernet

Question

Arduino

Comrades, I'm tormented by what to take the W5100 or Enc28J60. The device will collect information from sensors and send it to mysql. I would take wi-fi, but it turns out to be expensive. At the moment I take uno and w5100. Then most likely I will make my payment. And how else to ask. I thought poe, but the converter is big. Thanks

Answer 1

The advantage of the W5100 is that the TCP / IP stack is already implemented there, but for the Enc28J60 you will either have to write it yourself or use one of the existing ones. Although, of course, the Enc28J60 is a plus in its price. If you plan to use RTOS and you have enough RAM for this, then you can choose Enc28J60, otherwise I recommend spending money on the W5100.

Answer 2

I worked a lot and for a long time with arduino ethernet modules. Made a prototype for the project. At first, I tried long and hard to implement everything on the Enc28J60. All because of its attractive price - it was necessary to make a prototype in several copies. Everything works very crookedly, not reliably, well, and generally somehow damp. A lot of time was spent on enumeration of possible libraries. I tried to rewrite them, correcting glitches. As a result, I did not get it to keep the connection stable. Decided to go broke and buy w5100. I was surprised by his work. Everything works like clockwork and as written in the documentation. It's not even worth comparing. My advice is not to waste time and take the w5100. Basically earth and sky.

Answer 3

Maybe it's easier to take raspberry pi for such things, the simplest one? Plus there are options to power through POE.
