Single board ethernet microcontroller?

Google Groups
1

In people’s opinion, what is the cheapest option for an ethernet-connected
microcontroller board?

Looking for something AVR or ARM based, preferably under £20, any thoughts?

Bob,

I have had a search around because I’m interested in this myself. I can’t
find one…not in the price range you are interested in. To be honest any
Arm based processor will do but we then need to add the ethernet in software
and drive it. All doable but not available. Perhaps we should make one?
It would be a great piece of kit!!!

Regards

Alex

P.S. I’ll get on with the Theremino now!!!On Tue, Feb 22, 2011 at 1:31 PM, Bob Clough parag0n@ivixor.net wrote:

i know you asked for AVR or ARM, but i did see a while back a small ish
PIC with built-in ethernet, cant remember which one it was off the top
of my head thoughOn Tue, 2011-02-22 at 18:59 +0000, Bob Clough wrote:

the thing i found earlier. Arduino compatible and has an onboard PHY,
so
less code is needed on the arduino end.

Parts cost is about £12 each for this version. Might be worth pricing up to
make a SMT version with PoE, could easily see that selling for £30+. Going
to get the parts for one in a mouser order tomorrow, and if it works well
make 3 or 4 more for other projects.On 22 February 2011 19:03, Simon Hammersley bazbo85@gmail.com wrote:

That’s one tasty-looking ethernet transceiver chip. I’d certainly buy
SMT versions of this, especially if it came with a beefier ATMega on as
well…

What would you count as beefier? the one used on the Arduino Mega? or
bigger than that?

I think a mega would be mega enough :slight_smile:
