I would like to make a new design for my device that I would like to be using for the next 5-10 years.
I chose the Arduino Due board with SAM3X8 microcontroller which should perfectly match my needs. However, I see the SAM3x8 is already a legacy device, although still in production.
How long can I expect it to stay in production? Or should I choose rather a SAM 4 device? For that, however, I would need to design my own board with peripherals. What I like is that Arduino Due board is just perfect for my needs, but it does have SAM 3X8.
