The subject really says it all, but I’m wondering if the Olimex 28 pin development board JustWorks™ with a 28 pin AVR with the Arduino bootloader installed? If not, is it a simple matter to make the necessary changes? Is this a fundamentally stupid question in some way?
I’m thinking about these two products specifically:
ALMOST.
The DEV board has a 8MHz crystal - the arduino uses a 16MHz crystal, and all the timing-based code assumes it will be running at 16MHz.
Is their any reason you want to go down this path in particular?
If it’s because you want native RS-232 rather than USB, you could get this: http://www.nkcelectronics.com/freeduino … tib20.html. It’s the same price as the DEV board alone but includes the bootloaded AtMega168
The DEV board does have a nice prototyping area. You could get the above mentioned board + this prototyping shield http://www.nkcelectronics.com/freeduino … d-kit.html.
That said if you don’t have a specific need for RS-232 as opposed to USB, I’d highly recommend getting a USB version of arduino, like one of the ones Sparkfun sells (this supports the arduino developers) or one of the many clones out there.
Actually RS232 doesn’t interest me. I’m looking for the least expensive route to an assembled Arduino compatible.
edit: The Stickduino is the closest combination I’ve found so far. http://store.fundamentallogic.com/ecom/ … ucts_id=41

So if I swapped the onboard 8Mhz Crystal with

Or just compensated for any timing related issues in software, this combination should work?
Ultimately I’m looking for the least expensive simple way to get microcontrollers all over my house for various little automation things. I’ve so far found cheap or simple, and the Arduino (of which I have one USB already) seems to be the best average of the two.
As always, I’m ready to be persuaded otherwise.
Here are a couple of Sparkfun basic Arduino compatible boards that look comparible to the Stickduino , pricewise.

Have you looked at these?
I have considered those as well, but they have the disadvantage of needing an additional FTDI cable. Although I guess there could be a way to use the FTDI chip on my existing Arduino to program one of those two.
Decided that if I want “disposable” micros for tiny, simple projects the Arduino might be the wrong route. I ordered a couple of Picaxe 08Ms to play around with. I’ll use the 'duinos on more complex projects.
