It is with a heavy heart today that we mourn the loss of my Arduino Due board. Seeing as the only sketch I ever used on it was the blink sketch to test it, I was excited with the thought of a cool idea for that 12 bit adc so I popped this thing out of my storage bins and hooked it up. Checked and double checked all my connections, make sure no +5v hitting the i/o's...and then it happened...
I accidentally connected +Vin to A0. Now an internal short keeps the chip super hot with the power connected.
Being extremely proficient in soldering due to my job, i searched for a replacement SAM chip and found some for as little as just over $10, sweet! It would be cake to replace it! Then I learn that there is a ROM burned to the chip when the boards are assembled. Oy,
Its as good as parts. RIP.
