Hello all,

I am planning on buying a programmer board and I was wandering what
the real difference is with the stk 200 stk 500 boards.

Could somebody point out to me why to get the one or the other and what the
strong/weak points are?

Thank you for your time,

John

Hi John!

I hope more people will contribute with their experiences of the STK200 vs the STK500, but here are some comments:

The STK500 is meant to replace the STK100 and the STK200, and to be an improvement. I think it has succeeded. Both these boards are now obsolete as far as Atmel is concerned, but Kanda supplies the STK200 as the STK200+. As I see it, the main reason for choosing STK200 above STK500, is the price. The STK200+ costs about US$59, while the STK500 is approximately US$79.

The STK500 supports all AVR devices with the current exception of ATmega103(L). It can do serial/parallel high-voltage programming, which the STK200 can't. If you do a search of the forum on "fuse bit", you'll see that this feature is frequently needed. The STK500 further features an on-board programmer which interfaces directly with the AVR Studio developing environment by means of the serial port. This makes development easier. The STK200 needs the AVR ISP software, which currently doesn't support the Windows NT/Win2k platforms. The AVR Studio runs on all Windows platforms.

There are several other STK200/STK500 discussions further down in the forum, which might be of help, but I recommend the STK500 if you think you need any one of the features I've listed here. To buy the STK200+, contact Kanda at this link. To buy the STK500, contact your local Atmel distributor.

I'm an Atmel FAE, so I think some unbiased STK users should perhaps make further comments. Some already have, as I said, further back in the forum. However, I think my view is rather objective.

Hi again!

I think the links were corrupted in my last posting. I'll try to remedy this:

Kanda web shop: here
List of Atmel distributors: here

I would go with the 500, actually I have a 200, a 300, and a 500. The 200 uses a parallel port dongle for its interface, and there is a slight risk of system damage. The 500 connects via a serial port which is a lot more tolerant of overvoltages. The 500 also lets you set the VCC and AREF voltages from inside Astudio (very accurately I might add), and vary the clock speed as well. All in all a much more useful system.

Hi!

As I know STK500 doesnt have LCD circuitry and LCD connector. It's pity becase as far as I know there are many people working with LCD and AVR.
It would be great if your board allowed easy LCD connection in external memory mode.

Best regards,

I was told the STK200 is no longer available.....

so I HAD TO buy the STK 500... btw.. i'm real happy I did!!!

GREAT BOARD!!!!

and about the lcd connector....

i have connected a LCD with backlight...

works great!
and by the way it works via the normal com ports....
so you can use ISP.....(in system programming..)
great work ATMEL!!!!!
