It supports up to eight simultaneous socket connections. Use the Ethernet library to write sketches that connect to the Internet using the Shield.

The Ethernet Shield 2 connects to an Arduino Board using long wire-wrap headers extending through the Shield.

The Ethernet Shield 2 has a standard RJ connection, with an integrated line transformer and Power over Ethernet enabled. There is an onboard micro-SD card slot, which can be used to store files for serving over the network.

It is compatible with the Arduino Uno and Mega using the Ethernet library. When working with this library, SS is on Pin 4. The original revision of the Shield contained a full-size SD card slot; this is not supported. The Shield also includes a reset controller, to ensure that the W Ethernet module is properly reset on power-up.

Previous revisions of the Shield were not compatible with the Mega and needed to be manually reset after power-up. The current Shield has a Power over Ethernet PoE module designed to extract power from a conventional twisted pair Category 5 Ethernet cable. For more information, see the datasheet The Shield does not come with a built in PoE module, it is a separate component that must be added on.

This is on digital pins 10, 11, 12, and 13 on the Uno and pins 50, 51, and 52 on the Mega. On both boards, pin 10 is used to select the W and pin 4 for the SD card. If you are using both peripherals in your program, this should be taken care of by the corresponding libraries. If you're not using one of the peripherals in your program, however, you'll need to explicitly deselect it.

To do this with the SD card, set pin 4 as an output and write a high to it. For the W, set digital pin 10 as a high output.Today I released the Arduino Ethernet Library version 2.

Version 2. The chip detection process uses the Wiznet software reset command followed by 2 write and read-to-verify checks on the main configuration register, for very robust hardware detection.

Optimizations at multiple levels within the library work together to vastly improve performance, especially on the oldest W hardware, and also make the most of the newer W and W chips. A a tremendous amount of work went into these optimizations.

The 2. Here are details, from the highest to the lowest level. The Wiznet chips transmit and receive Ethernet packets with their internal buffer memory. Previously these registers would be read and sometimes updated for every access, using many bytes of SPI communication, even just to check whether data is available. A small amount of memory on the Arduino side is used to cache these registers, which greatly reduces non-data SPI communication. This allows Ethernet 2.

W chips see a tremendous TCP speed boost, because the delayed ACK feature was poorly implemented in that old chip. When your Arduino sketch reads or writes multiple bytes, these efficient block mode commands are used. Unlike other libraries for W or W, the efficient block most is also used with accessing 16 and 32 bit registers.

In addition to nearly cutting the register access time in half and register access is done much less often due to cachingblock mode also greatly reduces the chances that a register which may change will being read will need to be accessed more than twice to get the same value. Control of the CS pin in version 1. While very efficient, only certain boards were supported and using any other pin required editing the library.

On others, the CS pin control uses ordinary digitalWrite. Especially when communicating on with local devices on the same LAN, you might like much shorter timeouts. The connection timeout is how long to wait when trying to connect to a server, or for stop to wait for the remote host to disconnect.This shield and the chip upon which it is based forms the basis of just about every IP enabled networking project in the Arduino world.

The Wiznet W chip has some interesting features, such as direct and indirect memory access, but it has some severe limitations in its SPI bus capabilities. Also, the W can support only 4 ports within its hardware IPv4 engine. There are two major issues with interfacing with the W And second, the SPI interface supports only a byte mode transmission. Also, the W byte mode transmission requires a 4 byte SPI bus transaction for each byte of data to be transferred into and out of the network interface.

The W brings a number of new performance features to the game, based on the well known and understood IPv4 network engine of the W The table below contrasts the two chips. The W is a much smaller and simpler chip to locate on the board, and it is easier to solder for those interested in private SMD constructions. These features make the W a great performance increment on the W, and already sufficient to make a switch.

An example of the size of the two chips compared can be found below, with the Elecrow W on the left and an old DF Robot W v1. However, the greatest improvement in the W lies in the area of the SPI bus interface.

Wiznet has ditched the Direct addressing mechanisms that took all the pins on the W, and made the W a SPI specialist, capable of running at up to 80MHz clock.

That is a 20x increment. Additionally, the W supports SPI burst mode transmission.

ARDUINO ETHERNET SHIELD/BOARD

A practical analysis of the speed difference between the two Wiznet chips is here. These replacement drivers for the existing W driver files provided within the IDE just have to be substituted or overwritten to enable the slightly different SPI interfacing requirements of the W I was waiting for a long time for the W to be put onto an Arduino compatible shield, so that I could use it easily.

Suddenly, there are two on the market. I decided to purchase some of the Elecrow W Shields. They looked to have a much better design than the Wiznet version, because Elecrow have utilised proper 5V to 3.

The key and unique afaik feature of the Elecrow W boards is the use of the lowered RJ45 jack, that allows the Ethernet shield to between other boards with no clearance problems. I spent some time working with the Elecrow W, and have been in discussion with Richard and David Tech Support at Elecrow about the implementation. They have been very helpful in resolving some issues I have found in using their design. Firstly, they have used quite a high resistance on the PWDN pin which is intended to allow the W to be powered down to reduce energy consumption.

This can be solved by pulling jumper J to ground, or permanently by bridging Pin 1 and Pin 2 on U6 which is the buffer chip controlling the PWDN line.This started as a quick project to provide an alarm and phone notification when a water leak was detected in our second floor laundry room.

Older posts.I love the Arduino Nano - it's a nice compact yet fully functional version of the Arduino Uno.

Arduino Ethernet and SD card shield (WIZnet W5100)

However, when I went to connect it to the internet all of that neat and tidy smallness disappeared under the big full sized ethernet shield I had. See my other instructable on how to do that. However, I recently discovered a better, more compact way to connect my Nano to the internet - by using the much smaller and more affordable WIZio module from WIZnet!

You can get an adapter board to connect this module up to an Arduino Uno for easy connection, but I wanted to keep things compact by using my Nano and directly connecting them together. However, the same procedure can be used to connect it up directly to a Uno if you don't have the adapter board. I put them back to back see pictures to allow the USB power cable and the Ethernet cable to both be easily hooked up.

As you can see in the pictures, my breadboard would ideally have been 1 row longer! Also, the board itself should have a digit 1 by the number 1 pin. This should be the outermost pin on the side of the VIN pin. The WIZnet module uses a newer chip and requires an updated library for it to work. Don't worry, your older ethernet boards will still work with it too. See Note a in the Notes step if you need to also use other ethernet shields and modules.

For my WIZio it looks like this:. In the same file, optionally also uncomment the line that allows the board to use the pre-assigned hardware MAC address:. The picture shows what my settings look like I used XCode to edit the file, thus the nice formatting and colours!

Now that everything is all set up, it is a good idea to test it to make sure everything was done correctly. Thankfully, the Ethernet library includes a set of very nice examples. We will just use the easy WebServer example.

I used this:.

Note that this is probably not necessary for most networks, as long as the first 3 digits match your own IP address. Open up a browser window and load the url matching the IP address you set in the WebServer example. The browser window should just show a list of numbers, corresponding to each of the analog inputs.

Note that as we did not hook up any of the analog inputs, those numbers will be somewhat random.

You could of course start adding a bunch of sensors to them for more fun :. For example, for my other Wiz based ethernet shield, I uncomment the top line:. The W alone on the WIZio board typically sinks about mA from the datasheetand the output of the 3.

I do not know about the Nano, but I would expect similar. This would mean that connecting the WIZio directly to the 3. Reply 4 years ago. I wonder if the power into the nano is not enough to supply both? For my Instructable I was using a 5v version of the nano. Not sure if that makes a difference.
