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.
