Embedded Ethernet..

Hi,

If you want to move from PIC, look at RABBIT micros or Ziloez eZ80Acclaim.
As for the actual controller chip, look at CS8900.

cheap option as others have said is an isa ethernet card

http://www.ethernut.de/en/isa/index.html

get one from one of the weekend computer markets.
50c - $5 for an isa card, for $5 should be able to pic up a few.
Make sure to check what the chip is.

http://hyper.sunjapan.com.cn/~hz/PIC/index.html look at picnic
http://hyper.sunjapan.com.cn/~hz/PIC/picnic/hardware.html

For quick option www.edtp.com
packet whacker , nicholas or nicki board

Have a look at http://www.lvr.com/

Also enter the Zilog design comp and select one of the ethernet modules.
If they have any left.

I don't know if you noticed, but this website has the source, schematic and
parts list for the board you are looking at . It is $80 because this person
needs to amortize out the one time charges he got for making the nice
looking circuit board (and his time to solder them , if he is doing them
himself) and he wants to do it within 20 sales or so.
He isn't mass producing them because its not like General electric calls up
and says they want 10,000 ethernet modules for "pic" projects. This guys
target audience is probably schools and people like us who don't want to
absorb the cost ourselves or the effort.
I think if you were to make two of these "bare" circuit boards with no
solder mask or silk screen at somplace you would be charged a base $50 just
to start up the fab line + material cost. So in reality , to take all that
hassle out of doing it ,myself...i might just pay the $80. If you went out
and made ...say 10 boards for yourself and didn't do solder masks (say an
APCircuits proto run, like the guy shows in is web page) you might be able
to make them for $20 a piece.
You could probably find a "project converter" board out there that you could
solder this chip (the CS8900) to and stick it into a perf board for
soldering.
But all the information is right there on that website.

Thanks, you've been most helpful
