The Olimex P107 board comes with integrated ethernet. And they will release an improved F2 series board sometime this autumn. Or you could get an EtherTen from freetronics. Otherwise sure - make your own board design.</p> <p>As for the ENC28J60. The reason to avoid using that chip is due to how poor it is to program in software. And also the reason (by comparison) why the Wiznet 5100 chip is preferred.

I didn't mean to cut out the ENC28J60 out of the discussion, my intention was to get a hold onto the idea of having 100Mbit ethernet connection. And breakout boards in general are available everywhere but no 100Mbit and I wanted to design one for the community.<br /> But sure, I can also make a 10Mbit shield for it too. </p> http://forums.leaflabs.com/topic.php?id=244&page=3#post-5942 Tue, 09 Aug 2011 08:40:55 +0000 mikep 5942@http://forums.leaflabs.com/ <p>@Albrektson<br /> Was the Ethernet shield for the chipKitMax already released? It seems it is still delayed from what I can tell and no-one knows when it will be available.</p> <p>@dirtycookie<br /> Just out of interest, why did the ENC28J60 not make the cut in your list? Most of the cheaper Arduino Ethernet shields are based on that chip, there are tons of libraries and code out there for that chip, and it's also 10MBit chip. I had gotten the Maple to work with the ENC28J60. And theoretically it seems not that difficult to adapt the existing Ethernet shields to the Maple hardware-wise (e.g. just bypass the 3.3V regulator on the shield and take out/eliminate the level shifter on the MOSI/CS/CLK lines). Or just use a breakout board like this: <a href="http://cgi.ebay.com/ENC28J60-Network-Module-Schematic-51-STM32-LPC-AVR-/250839819197" rel="nofollow">http://cgi.ebay.com/ENC28J60-Network-Module-Schematic-51-STM32-LPC-AVR-/250839819197</a><br /> Now there are some different threads about the voltage regulators on the Maple being able to supply the necessary current (in my case I measured 120mA) to the shield, so it's probably better to have a separate regulator for the ENC28J60 or beef up the Maple regulator. </p> http://forums.leaflabs.com/topic.php?id=244&page=3#post-5941 Tue, 09 Aug 2011 08:06:00 +0000 dirtycookie 5941@http://forums.leaflabs.com/ <p>Hi there,<br /> I've been on the search for a while for a cute little embedded board that has USB and Ethernet capability.<br /> I have found 1 or 2 projects that are interesting but are closed source or are commercially driven.<br /> One of them is bifferboard: <a href="http://bifferos.co.uk/" rel="nofollow">http://bifferos.co.uk/</a><br /> A very neat thing but when asking for the schematics cause you would develop a different version, you would get dissapointed.<br /> Then I stumbled to you guys, live and kicking.<br /> So I thought I could share to you my findings that I gathered concerning ethernet controllers.

This connector is located where the Maple's large 2x8 connector is located. In order to make the Ethernet shield work, you'd have to solder jumper wires from the SPI pins on the ISP connector (without the connector being populated) over to digital pins 11/12/13 where the Maple's Hardware SPI 1 is located. It'd probably be easier just to get a breakout board for the W5100 that's not the Ethernet shield. Although, the Ethernet Shield version 1 uses digital pins 11-13 instead of the ISP connector. If you own that shield, it aught to work.</p> <p>Ethernet is something I'm interested in working with, but I have no immediate plans for it. I have two or three other libraries I need to write &amp; publish, plus I should be finding a job now that I've graduated. Because of all this, I wouldn't feel comfortable taking money from you and promising results as I wouldn't be able to guarantee them.</p> <p>If ethernet is crucial for your project, you may be able to get away with using an Arduino + the Ethernet shield, then communicate between the Arduino and Maple via USART or SPI. It's not ideal, as you'd be bottlenecked by the Arduino's limited flash, ram, and cpu, but it aught to be enough to get started.</p> <p>-robodude666 </p>
