See also the article "The Tuxgraphics ISP header" for a description of those adapters.

tuxgraphics to atmel 10pin

Adapter: tuxgraphics programmer to atmel 10pin connector (use our programmers with atmel development boards)

This is an adapter to use a tuxgraphics programmer with target boards having an 10 pin ISP-programmer plug.

Instead of buying it you can also build this adapter yourself: Circuit diagram, 10-pin-adapter.gif

price: 2.95EUR, [convert_currency]

Use case for this adapter: You have our avrusb500 programmer and you want to program a third party board (non tuxgraphics) with 10pin header.

Adapter: tuxgraphics programmer to atmel 6pin connector (use our programmers with atmel development boards)

This is an adapter to use a tuxgraphics programmer with target boards having an 6 pin ISP-programmer plug.

Instead of buying it you can also build this adapter yourself: Circuit diagram, 6-pin-adapter.gif

price: 2.95EUR, [convert_currency]

Use case for this adapter: You have our avrusb500 programmer and you want to program a third party board (non tuxgraphics) with 6pin header.

Three tuxgraphics ISP sockets

Three tuxgraphics ISP sockets. These are standard 5-pin sil sockets with 2.54mm pin spacing. Instead of buying them here you can also use a normal IC-socket, cut 5 pins off and you have your own socket.

price: 0.75EUR, [convert_currency]

6pin-atmel to tuxgraphics adapter (to use a programmer with a 6pin header with our PCBs and kits)

Use this adapter if you want to program tuxgraphic kits and target boards with a non tuxgraphics programmer.

price: 2.99EUR, [convert_currency]

Use case for this adapter: You don't have our avrusb500 programmer. You want to program tuxgraphics boards with some non tuxgraphics programmer that has a 6pin header.

10pin-atmel to tuxgraphics adapter (to use a programmer with a 10pin header with our PCBs and kits)

How to connect VTG? What is VTG?

The tuxgraphics avrusb500 needs only 5 pins but other programmers may require an additional pin called VTG in order to function. This pin is usually used to power the programmer hardware itself. The "atmel to tuxgraphics adapters" have therefore on the side a little flat metallic area where you can attach a mini crocodile clamp. You need to connect this to the same voltage which is used to power the microcontroller, e.g internal 3.3V in case of the ethernet board. Some of our boards do even have a connection near the programmer connector called "VTG". Attach the other end of the crocodile clamp to this pin.

Why does the tuxgraphics programmer not use this pin?
The programmer connector is a temporary connection and will never be used again once the system is ready. It makes therefore sense to keep this connector as small as possible in order to minimize the space needed on the board. This VTG pin is obsolete when the programmer is powered via USB and it is not even required to sense the voltage level of the target. Our avrusb500smd can sense the target voltage and adjust in the range of 1.8V to 5V. Other manufactures do however continue to use the VTG pin even for the USB programmers.
