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.http://www.ebay.de/itm/TAIJIUINO-Due-Pro-Board-completely-compatible-with-Arduino-Due-/130825173003?pt=LH_DefaultDomain_0&hash=item1e75c9b80b#ht_6491wt_1144
Im using this Circuit to build minehttp://arduino.cc/en/uploads/Main/arduino-Due-schematic.pdf
Is there a complete Pinmapping for the due available? Since the Diagramm on the arduino page is incomplete.
