These two solutions seem comparable to me. I still don't understand why adding Ethernet to an Arduino costs more than the Arduino on its own. I appreciate costs go down with volumes but an Ethernet shield is still at the top end of shield prices.
eried: That is an ENC28j60 chipset, not a Wiznet. It will gobble up the ram on an Uno like nobodies business, and the standard ethernet library doesn't support it AT ALL.BTW: If you think the ethernet is expensive, look at the WiFi.. EeeGads.. I suppose if you HAVE to prototype a WiFi setup... Remember the Arduino is just an educational/prototyping platform. Prototyping is generally always more expensive than mass production, even if this is prototyping on a mass scale.
