I don't know of many "shield"-type add-ons for raspberry pi, and I've never seen an ethernet one. Since the built-in NIC is USB, I'm curious why you eliminate USB for a second NIC. Without more details about what you're doing, maybe a routerboard, or a linux router (I LOVE my ASUS RT-N16), or a cubietruck would be more appropriate if you need more and/or faster NICs. > I know there are "Ethernet shields" for Arduino, > but then I'd have to write a heck of a lot more code to do the same thing > as I can accomplish with Raspbian on the Pi and a board that provides an > extra Ethernet port. You can't write "a heck of a lot of code" on most Arduino's. For my daughter's science fair project this year, we started with a sample program provided with the CO2 detector to just monitor the detector, and display the result on an LCD display shield. By the time I added a couple of lines to log the data to the serial port (captured by a raspberry pi), over half the arduino's program memory was full. That's less than 100 SLOC on an Uno R3. If you really need the I/O connections on the duino, and the networking and linux of the pi, I would add something like this to a pi: http://www.dfrobot.com/index.php?route=product/product&product_id=1148&search=raspberry&description=true FWIW, Barry /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
