          If you are in the USA, forum user W3DRK may be able to replace the MPU for you.

            Hi Dave,

            Just checked my original order and it was in September… so I guess it is still under warranty! I am in South Africa, so what do I need to do to claim? I have ordered another in the meantime.... but it would be good to have a spare...

              If it was delivered in September 2016 not 2017 then it is out of warranty.

              Do you know anyone local to you who can replace the processor? If your soldering skills are good enough you could try it yourself. Use ChipQuik or similar low melting point solder and a cheap vacuum pick up tool to remove the old one. There are videos on YouTube.

              Btw the more recent Duet versions have improved protection for the ADC.

                Oh gosh you are right 🙂 sorry late night !! I have dome some SMD repairs before so I will take a look when I remove it. Dot think I have done so many legs before though (older Atmel stuff mostly)

                  The tricky part is removing the old chip without lifting the PCB traces. You need either a good desoldering hot air gun with an appropriately sized nozzle and a vacuum pickup tool, or ChipQuik or similar low melting point solder (and preferably the vacuum pickup tool too). If you succeed without damaging the PCB, soldering the new chip in place is relatively easy if you have a no-clean flux pen, also some solder wick to help remove the inevitable solder bridges.

                        Not without knowing which country you are in. Here in the UK, Farnell, RS, Mouser and Digikey all sell it.

                            Yes that's the correct one.
