Hello I am looking for a prototyping board for my students. I have seen many for the mega128, but would prefer to use the tiny26. I would like something along the lines of the stk500, but with more prototyping area & maybe a small lcd on the board. Does such a small board exist? I don't need all of the sockets for every type of AVR, just the tiny 26.

I've looked at some of the boards in the tools section, but have come up dry.

Olimex makes dev boards for 8 pin and 28 pin avrs. Did you look on their site?

Why not use the Mega8 , if you buy the 28-pin Olimex board then the M8 fits right in , and it has got more Flash & Ram.
http://www.olimex.com/dev/avr-p2...

I'd suppose the T26 vs.M8 price difference is "nothing" compared to the boardcost

The M48/M88/M168 are pincompatible with the M8 , so those would fit in the same board.

If its for students you might want to look at the Olimex 40-pin board , as they will have a lot more pins to play with (for lcd etc..) , the 40-Pin board accepts M8535/M16 and M32.

And the price is the same as the 28-pin board ($14.95)

Programmers ($9.95)

Serial

Parallel

If you are on a Really tight budget then you could just buy 2 programmers , and preprogram the M8/M16/M32 with Microsyl's bootloader.

Then students can load programs (avr selfprogramming) directly from their comport.

All the above boards comes without CPU and without Wallwart , but they have 5v-Reg + 8Mhz Xtals + RS232 drivers onboard.

So buy some CPU's and Wallwarts off ebay or ask Atmel for the CPU's

Another option is to use the AVR Butterfly with a solder less breadboard. Check out http://smileymicros.com/. Download Smiley's free Quick Start Guide.

I can say that Olimex makes quality products that work. I have several of their boards and programmers and will buy from them again. I was a little hesitant to order at first, but they really came through.

Another good bet is the Butterfly and the SmileyMicro book, which was worth every penny I spent on them. The book and the Butterfly are fantastic products.

Long story made short. Hardware class: I suggest Olimex boards. Software class, I suggest the Butterfly and the SmileyMicro book.

Hi,

How about having the students design and build what you are looking for? Sounds like it would be a great 'real world application' learning experience (in my opinion :-) ). You could use the free version of Eagle or the ExpressPCB free CAD software. It could be a class project and that way the students get to learn how to work as part of a team. They get a taste of PCB assembly and soldering. Real world experience (or lack of) was the major complaint I had of my 2 year degree program (20+ years ago :-) ).

Anyway, just throwing out ideas.
Regards,
Steve
