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.
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.
