Hi!

I want to etch my own Board with a due. What do I really need to get them to work? I want to flash the Chip with JTAG. So I dont need the Config 5V Circuit with the Tiny. What about the erase circuit? I planned to use a simple button to reset the Chip since I dont need a automatic circuit for this.

It would be more simple if I could use the USB Interface. As described in this clone, they left out the Tiny Chip.

Im using this Circuit to build mine

Is there a complete Pinmapping for the due available? Since the Diagramm on the arduino page is incomplete.

Hi, Thanks! But I was looking for a Pinmapping like the atmega has (for the Chip only).

Like this

I don't know of any drawings like that for the Due. Most of that information is in my diagram (chip pin numbers etc) but in a PCB-centric layout not laid out as seen on the chip.

no drawing of the chip, but the same table is here:

But the Chip has 144 Pins, or am I wrong?

Graynomad

Correct, and that table doesn't show the physical pins which I gather is what you want.
