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. Tony

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. http://www.jandspromotions.com/zilog2004/ Alex

Hi,

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

One possibility (may require basic Japanese :-) is AKI-H8/3069F LAN board: <http://akizukidenshi.com/catalog/items2.php?c=h8kit&s=popularity&p=1&r=1&page=#K-00168> It has H8 processor (w flash) and RTL8019. 8700 Yen is less than $80 (US). Not affiliated with the company in any way (except as a happy customer). -- @jhol Ihmisi&#4294967295; ei voi ostaa, heid&#4294967295;t voi vain vuokrata.

http://www.edtp.com/ has a couple of boards you might be interested in. They have a RTL8019AS based board Packet Wacker) for $35USD assembled, or a CS8900A based board (Nicki) for $50USD assembled.

$30 to $90 in six months! Surely a different thingy? The SMSC91C9x devices are easy to write code for, and the CS8900 is fairly easy, so go with one of these. If you haven't got it a copy of Jeremy Bentham's book "TCP/IP Lean" is a must.

If you really are after learning, why not simply purchase a CS8900a chip alone and wire your own board? If you use http://focus.ti.com/lit/an/slaa137a/slaa137a.pdf as a reference it should not really be such a big deal. Markus

Thanks, but that one is $90 and already has tcp/ip stack.. This will sound silly but I am already writing my own so only need 10baseT Ethernet connectivity for the PIC mcu DaveC

you might consider   IPu8930 from IPsil
http://www.ipsil.com/products/d8930.htm

Available from Adilam Electronics in Australia   www.adilam.com.au

Comments  - Ipsil has preliminary data on their IP&#4294967295;8932 which combines a
webserver, Ethernet MAC layer, and TCP/IP controller all on a single chip.
This allows the one chip with 20 digital or analog inputs to display
webpages without the need of a microcontroller. Ipsil has WebHolesT
technology which allows holes (simular to server side includes principles)
to be filled in with values from the I/O ports. If you do happen to need
more complexity, you can add a microcontroller and talk via standard TCP/IP
socket calls.
