Interesting, my pack was pre-seperated with no solder in the holes.

The adapter pack was fine. The solder was in the at90usbkey board.

The adapter boards are scored by the PCB manufacturer. You can use your fingers or a pair of pliers on the edge of the boards to break them apart. I wouldn't use a knife for this.

I've heard from a number of folks that the AT90USBKEY header pin holes have solder in them. They may have changed the board assembly service they are using, stopped masking the holes to save cost, or both. I'll send an email to Atmel in France (where the AT90USBKEY is designed) and inquire about this.

Actually, now that I realise what he's talking about, it's a known problem. A user here posted a warning a month or so back saying that the latest batch wasn't masked correctly and so the holes are filled. I'll try to dig it up.

EDIT: That was easy!

Thanks, Dean. Do you have a contact within Atmel that I can send an inquiry to about this? PM or email me if you do.

Ok, the board here seem to be marked with 2008.09. Any idea what should I do to install the header adapters? I guess Atmel is not going to send me a new board for something like this?

I would use some solder-wick to remove the solder from the holes. Sometimes it helps to add more solder to the holes before you use the solder-wick.

Or try some extra flux.

Some people even use solder wick soaked in flux. Not my cup of tea, but it seems to work for them.

Stealing Proteus doesn't make you an engineer.

I managed to remove the solder:
1) I attached the board to a vise vertically
2) I then used a very small soldering iron to heat one of the header holes
3) I then used desoldering pump on the other side of the board while simultaneously heating the hole with the soldering iron.

Hi there,
Are these adapters still available? I tried to place an order through the website but did not hear anything back.

If anyone could help me or let me know I would appreciate it greatly :)

Thanks,
Dan

Never mind! I received the adapters and installed them. Now time to learn some AVR coding. Thanks so much!

Cheers,
Dan

Hello Tom!
Do you still have 10017 boards available?
Thank you,

Hello!

I was wondering if these expander boards are still available?

If not, could anyone suggest a way I can easily access the pins for ports A-F of the AT90USBKey?

Thank you.

Hi Tom,

I was also looking for the header adapters. Can they still be bought somewhere?

Regards,
Jerome

I haven't seen Tom on the board for a while. His last post was on his trip to Iran and his website seems inactive. :(

Update: I do see a Twitter message from him on July 24th, so that is at least a little more recent.

Regards,
Steve A.

The Board helps those that help themselves.

I know this is an old thread, but I wanted to document my solution to the header problem.  I've posted in this thread: https://www.avrfreaks.net/comment/1495712#comment-1495712

 

Cheers,

Tom
