AVR-Chat

I have an immediate need for at least four boards that support a dual-
uart AVR.  I really don't care which, as long as it's got two uarts, 
like the M128.

It is very important that the board be physically small.

I need the serial driver (max chip) and pads on the I/O pins, xtal and 
other support stuff, but nothing else.

Ideally a pre-assembled board.

Any ideas?

I personally love the Robostix:

How small is small?

Too small.. No 232 drivers, xtal, or support components.
But, you're thinking in the right domain.

I have one of these. Can't beat the price.

No on-board RS232 though.

Both RS232, RS485 or 1 of each? :)

So either M162 or M164/324 in the smaller package chips.

Both 232.  I could use 485 to talk to the host, but it's also got 232,
and there's really no reason to go 485.

128 has a slight preference, as I have app templates for it, but only
a slight preference.

You may want to check this one out:

It has all the features you are looking for, although it may not be 
that small.

Best regards,

Hans

Yup, relatively huge. :(

The one from germany looks good, I just wish it was a closer source.
I have most of the code written already, two fulldup interrupt driven
buffered serials, circular buffer logic, etc. I could probably finish
the job tomorrow if I had hardware in my hand.
