Arduino Ethernet Shield R3

Eth R3 Banner
Got myself an Arduino Ethernet Shield R3, the latest revision.

I made an unboxing video for it, though it may be boring to some of you but I hope it’s at least informative 🙂

The box.

The header pins are gold plated.

The Wiznet W5100 chipset, the heart of the Arduino Ethernet Shield.

The Ethernet Shield stacked on top of the Arduino Uno R3.

The Shield also includes a microSD card slot and it is supported by the official SD Library.

The 10/100 Ethernet jack.

To test it, I used a sample sketch found on one of the articles on,
Arduino R3: Testing Ethernet Shield R3.

Before that, I plugged in an Ethernet cable from the Shield to my switch.

Basically, the Arduino serves up a webpage where the user can turn an LED on or off.

The LED is connected to Digital Pin 8.

More exciting projects coming soon 🙂

    Fun fact: You can have a REPL on an Arduino! Just set up a serial cnooectinn, and run Forth on the device. (I could even imagine wiring up a serial port on the final project, to be used for debugging purposes )I can’t remember if I shared this fact with you at the Open Source conference, but even so, it’s something to keep in mind.
