Who would have thought a US$35 computer would change our lives so much. The Raspberry Pi foundation have changed the way we learn, teach and innovate by bringing a hardware platform which is cheap enough for the ‘average joe’ yet powerful enough to drive some of our most ambitious ideas. I have no doubt in my mind that I have left some info out here. Please feel free to leave a comment below to educate me a little bit! happy for input. I’ll keep updating this timeline as new releases come out. Thanks.

The Alpha Boards

Announced in August 2011, the ‘Alpha’ boards were among the first revisions. The Board itself was of a large format for debugging, was populated with headers for GPIO, JTAG, DSI, CSI and switches for LED and I/O testing.


Raspberry Pi First Production Board

Announced in 29th February 2012, The first of the “credit-card” sized computers was released. The initial batch of 10,000 (All Model-B’s) which were manufactured in China.


Raspberry Pi Model B

The RPi full production board – Model B Rev 2.0 was announced in April 2012, first orders were not sent out until June 2012. Manufacturing and orders were made via RS and Farnell. This meant that higher volumes of units were produced and made available. September 2012 saw the announcement of Model B rev 2.0 also being manufactured by Sony.


Raspberry Pi Model A

As of February 2013, the Model A was made available from distributors in Europe. The board had 256MB of RAM rather than the originally planned 128MB. The RPI foundation produced a small Beta batch of boards before handing over manufacturing to RS and Farnell. The Model A boards use an identical Rev 2.0 PCB but come with a different selection of components fitted.


Raspberry Pi Model B+

Announced on the 14th July 2014 The Model B+ was the first of the new layout. The B+ featured a new and faster processor, new VideoCore, 512MB RAM, Micro SD, 4 x USB slots, HDMI and many other upgrades.


Raspberry Pi Model A+

A few months after the release of the B+, the RPi foundation released a lower-cost variant labeled ‘A+’, At a new low price point of US$20 it was a smaller form and only a few components had been left out. But from an IoT perspective, it was still a very powerful unit for embedded hardware projects.


Raspberry Pi 2 Model B

Announced n 2nd February 2015. The RPi 2 Model B+ retained the same US$35 which was key to the continued success of the platform. The RPi 2 featured another upgrade to the CPU and an upgrade to 1GB of RAM. Other changes were also made.


Raspberry Pi Zero

The Raspberry Pi Zero was released in November 2015. The idea behind the Zero was a cheaper/smaller form factor that could be used to embed inside smaller projects. On 28th February 2017, the foundation then released the RPi Zer ‘W’ which had built-in wireless and Bluetooth.


Raspberry Pi 3 Model B

Another upgrade to the CPU (1.2Ghz 64-bit quad-core ARM Cortex-A53) was announced with a new release of the RPi 3 Model B on the 29th February 2016. Again the Raspberry Pi foundation achieved the same US$35 price point.


Raspberry Pi 3 Model B+

Announced in “Pi Day”, 14th March 2018. The Raspberry Pi 3 Model B+ is an incremental improvement over the previous RPi 3 for the same US$35 price.
