Official Arduino Ethernet Shield

Arduino has just released an official ethernet shield. It’s based on the same WizNet W5100 chip that was used in the tiny ethernet board we covered earlier. The W5100 handles the full IP stack and can do TCP or UDP with four simultaneous sockets. The board has a power indicator plus six LEDs to debug the connection. It works with the standard ethernet library. The reset button resets the shield and the Arduino. The SD adapter is not currently supported by the Arduino software.

  1. The hardware is there for the card slot, just the software library hasn’t been completed yet.

    It will be great for storing web pages and content for the ethernet server without having to use up the limited amount of onboard storage provided by the Arduino.

  2. It’s a small mammal that is typically found in south america. Lots of people are building hardware and sticking into the backs of these poor creatures causing them pain and forcing them to run their experiments.

    You can learn more about them on this secret website that has information about everything on the planet, dont tell anyone, it’s very secret…

  3. wow, what a way to be an epic douche fartface. i hate the internet becuse of people like you :D onos, i have to actually help someone learn something? nah i’ll just ridicule them and make myself gain internet badass points.

  4. @lulz,
    He was a bit too harsh. I suggest people abandon anonymity and start be having in a way that they would want their future employers to find on Google. But in fairness, you should always preface a question like yours with, “I’ve done some research on Google, but I’m still a little unsure of…” The hostility is the result of the overwhelming number of people who think they deserve a personalized answer to a common question because Googling is below them. That may not be you, but you want there to be no question.

  5. Does anyone know if it would be possible to use this for data logging? Writing a CSV in FAT would be amazingly helpful. Even if you were to interface with the card in raw mode and write to specific locations. I’ve looked around and I’m stumped.
    Help will be much appreciated!
