No, I don't need one but I get asked from time to time where to buy one or if I have any around.

Sparkfun has something http://www.sparkfun.com/products...
and possibly others but I have produced a PCB to use any Atmel 6 pin programmer header with "stuck in the past" :-) boards which use the 10 pins headers.

Don't know if it works, it should as it is very simple.

The 6 pin ISP header should be mounted on the top side of the board and the 10 pin header at the bottom. The design is a double sided board for mechanical strength of the 10 pin header, as it would be plugged in and out of the boards, but the tracks are only on the bottom layer so a single sided board should also be possible with a bit of care soldering the 10 pin header under the board.

Pins 1 are the square pins of the 2 connectors, also there is a hole next to pin 1 of the 6 pin header. As this board may be made without an overlay the hole may be a good marker.

These are the Gerbers for all the layers with the .txt file telling which layer is which.

If you do make one and it works (or not) please let me know.

I made 2 of em using a 6 pin IDC cable and a 10 pin IDC cable and 10 wire nuts.

Bob,

That must be pretty, we need a picture. :) What did you do with the extra 4 nuts?

I have a spark fun one. It goes in a small zipper case with pololu programmer, Saleae LA, USB jump drive, 3 single header jumpers, and small phillips/flat screw driver. That kit makes me feel like I am loaded for bear, well an AVR animated bear. :)

It all starts with a mental vision.

You mean everyone doesn't have one of these sitting on their bench? :wink:

I've always found that one of these caters for pretty much everything I want to do (it comes free with a JTAGICEmkII)

But, you have to be smart and know colors and pin numbers. :)

A bit like a pilot with a checklist - rather than trying to remember the mapping - I simply read it from the checklist (or rather Dragon/ICEmkII manual) every time. ;-)

I see, so there are a lot of "stuck in the past" board users around. :lol:

Ever since I have used AVRs (about 12 years now) I have always used a 6 pin header as the AVRISP Mk1 I purchased used that so I thought that was the standard.

Had a good look around the workshop to see if I had ANY boards with a 10 pin ISP header and as hard as I looked I could not find any.

Anyway JC is you want you can even get the original PCB file as you have a special software package that can open the file. :wink:

I'm a nut.

I think the additional 4 pins are for rxd , txd , vcc & gnd so simply seperate it.

Meh, why bother with a PCB *or* a cable for an adapter?

The Olimex '128 breakout board in the pic is the only reason I made a 6-to-10 adapter.

Where squids are required (usually when I'm too lazy to wire a proper ISP header on a protoboard project), I find a bit of fine-tip paint pen helps prevent boo-boos.

I only use 10 for JTAG but 6 for ISP. The advantage of a "squid" is that you don't have to connect ALL the wires if you don't want (even down to just 2 for dW). For me the advantage is that you can connect to disparate pins on a breadboard and don't need to worry about grouping 2x3 or 2x5
