Can anyone recommend a good AVR development board for doing a temperature data logger? This would ideally already have bunch of flash memory for the logged data and a lcd display already built on.
Any help is appreciated.

try the AVR butterfly

... using what kind of temperature sensor?
-- Hans-Bernhard Broeker (broeker@physik.rwth-aachen.de) Even if all the snow were burnt, ashes would remain.
I've got a butterfly on back order from digi key but I'm sick of waiting for it. For the temp sensor, I was looking at a national semiconductor lm34.
See the AVR Butterfly Evaluation Kit - User Guide
Page 7; 2.1
Its ready for you to use.
RTFM

Did you ask Digikey for a reason behind the delay? I'm curious about their answer.

It's out of stock at Avnet and Arrow as well. I guess Atmel can't make this loss leader any more. The components are worth more then the board, we have a couple of them without the MCU and some other components. It was quicker to remove them than to order the parts.
I liked my experiences writing code for Atmel parts before. One seriously bad experience, plus an industry wide event over a period of perhaps 18 months regarding atmel and their apparent lack of support for partners other than a few very large ones, together made me walk away from Atmel until things demonstrably changed to repair that loss of trust. Sometimes I wonder if avoiding Atmel in those years since should be revisited. But this puts me a little on edge, again, and perhaps feeling that a little more time is yet needed to repair the faith.
Well, maybe there is another explanation and this can be disposed of.

I would disagree. I find Atmel to be quite supportive in the development process. The butterfly served it's purpose in bringing lots of attentions to the lcd chip. Although a bit more expensive, the AVR dragon would replace the butterfly in developing other chips. Atmel is in the chip business, not in development kits.
May be. For the amateurs or the beginners. Not for the professionals.
The Atmel AVR datasheets do not specify many of the important parameters. Such as a current consumption when programming the flash memory, for example.
The application engineers can't tell you anything other then you can find yourself in the datasheets.

Our local Atmel FAE is dedicated and has been excellent, where possible. I've no complaints on that score. There are other fundamentals involved, though.
I'm not trying to shape Atmel. I've had my experiences, nothing can take any of that away. I have decades of experiences with other companies as well. Nothing can take that away from me, either. And I'm perfectly capable of comparing those and making decisions. Of course, Atmel is a lot more than my experiences. Granted.
My only comment here was simply about the possibility of investing more time, once again, soon. I may still do that.
I'm very glad to hear that you've had great support.

Can anyone recommend a good board besides the butterfly? One that has a nice size piece of flash memory and a lcd on it?
What do you need to show on the lcd? Can you settle with led display?
We are hoping to release our iAVR-2561 in October. Small USB enabled M2561 boards, can take its power from USB etc. Email me if you want some prelim. info.
