    Note that it has the necessary “Wait for sensors to stabilize” code, among other things

    Regarding the LED on 13: Duh!! I think I forgot that a “pinMode(13,OUTPUT) would be needed to make the LED go properly "on” or “off”. (Before I remembered that, I looked closely at the board… it does seem that JUST the LED, and its resistor, are on pin 13. (My Ethernet Pro is not tied up with “a job”, or I’d go off and test whether I forgot the pinMode statement.)

    The Quickstart guide says… “Pay special attention to how you power the BMP085. Its maximum supply voltage is 3.6V. So don’t go feeding it 5V!”

    Loving my Ethernet Pro!
    One (more) question… Am I missing something? Schematic makes me think that on digital line 13 there is an LED, tied through a resistor to ground… Green, marked “L”, just above the W5100?
    But I couldn’t get a “clean” 0v or 5v on D13’s connector, and the LED never glows brightly. Usually a faint glow. Sometimes dark. Usually about 1 volt.
    No, I haven’t done anything nasty, like configuring it as an output, setting it high, shorting it to ground. Yes, I’ve tried a “blinky” program… I can “work” the another pin okay, but when I change just the pin number assignment in the program, pin 13 doesn’t “behave”. (I didn’t have an LED on the other pin, just my voltmeter… but several LEDs are shining very brightly, elsewhere on the board.)
    Is line 13 connected to anything except the LED and resistor? I believe line 13 goes high briefly on board reset (built into OS), but is there anything else going on in the Ethernet Pro, on line 13?
    Speaking of lines… am I right in thinking only lines 9-12 are used for the interface to the ethernet part of the board. All other lines “free”, for user’s use?
    I’ve put a small server into my Ethernet Pro… not a WEB server… something simpler. Details at…
    Enjoy!… I hope you will find the ideas there useful.

    The “BUB” from ModernDevice… oops… or the Sparkfun equivalent!!!… cost next to nothing, compared to the doors they open. You can, once you have one, have multiple Arduinos without paying for multiple FTDI chips… which you will typically only use when programming the Arduino, and don’t need once the Arduino has been put “in service” in whatever you wanted it to do. In other words, it rapidly pays for itself. Sparkfun’s 5v i/f: DEV-09716 $15… but get the 3v3 version, if that’s what you need. (ModernDevice’s BUB has a jumper to switch between the two voltage choices.)

    Providing an “out of the box” demo is difficult because you have to know what MAC addresses and IP addresses are not yet in use on the LAN the Ethernet Pro is going to be plugged into.
    Yes… it would be possible to send them out with known MAC/ IP addresses, and advice to the customer to unplug anything already using those before trying the Ethernet Pro out of box demo.
    But the customer who understands that, can probably load the test program of his/ her choice anyway.

    It would be easy enough to create an “empty” shield, with a cut-out to allow for the Ethernet connector. Then the stack would be….
    Whatever shield you wanted
    The “empty” shield
    The Ethernet Pro

    Freetronics also offer the EtherTen without the PoE module, for less… but still more than a Ethernet Pro.
    Why this talk of “cloning”? Such an obvious product was bound to be produced by more than one supplier, surely? I for one am glad of the chance to choose an supplier, and to feel confident that if either one stops selling their Arduino-with-ethernet, there will still be one available for any apps created for it.

    Seeing as the Ethernet Pro is described as “Ethernet shield on an Arduino Pro”, and that 5v and 3v3 versions of the Arduino Pro are sold by Sparkfun, and the, I would assume, dire consequences of attaching 5v to a 3v3 device, I would have thought that the question above would have prompted a clarification in the “official” product description. I don’t know if I’m on the road to disaster, but I have an Ethernet Pro that arrived today, and I am programming it with a ModernDevice “BUB”, with a wire link in place (necessary, to whatever voltage is right for the Arduino being programmed, for devices with Optiboot) by the way) selecting 5v… and my system is working so far… but haven’t been using it long. The regulators are quite warm, the Wiznet almost hot enough to burn the back of my finger. This with BUB connected, supplying 5v, but nothing else plugged in, although a program is running, a little server… but with no LAN connection at the moment, it doesn’t have any “serving” to do.

No public wish lists :(
