I am using several Raspberry PI 3 B for embedded applications. Given the release of the new PI 3 B +, I am now concerned about for how long the PI 3 B will be available. What is the expected end of life of the 3 B model ? Do I need to start migrating to 3 B + pretty soon or I still have some years ? Thank you very much in advance Guillermo
This isn't super easy to answer with any kind of guaranteed answer, but they did touch on this during the 3B+'s release post on the official blog.
Are you discontinuing earlier Raspberry Pi models?
No. We have a lot of industrial customers who will want to stick with the existing products for the time being. We’ll keep building these models for as long as there’s demand. Raspberry Pi 1B+, Raspberry Pi 2B, and Raspberry Pi 3B will continue to sell for $25, $35, and $35 respectively.
They offered similar answers when the other models had upgrades available, and they're still making most of those. Personally, I'd expect the 3B to be around for a while yet.
I've asked the charity for the EOL date of the pi-3b by email and today's answer was:
Raspberry Pi 3 Model B will remain in production until at least January 2022.
By the way: For the following devices is an "obsolescence statement" publicly available:
End of life of the Raspberry Pi Zero is currently stated as being not before January 2022
will remain in production until at least January 2023
