The Raspberry Pi is a series of small single-board computers developed in the United Kingdom by the Raspberry Pi Foundation to promote the teaching of basic computer science in schools and in developing countries
The Raspberry Pi Foundation started a teacher training course called Picademy with the aim of helping teachers prepare for teaching the new computing curriculum using the Raspberry Pi in the classroom. The continued professional development course is provided free for teachers and is run by the Foundation's education team.
In January 2017, a free MOOC course launched on Kadenze in collaboration with University of New South Wales in Sydney Australia on the Internet of Things using Raspberry Pi Online Rpi Course. There are also good online resources for Raspberry Pi on Sparkfun site as well as the Raspberry Pi Organization community.
By November 2016 they had sold 11 million units, and 12.5m by March 2017, making it the third best-selling "general purpose computer".In July 2017, sales reached nearly 15 million.
The Raspberry Pi Zero, a US$5 model first introduced in 2015
Several generations of Raspberry Pis have been released. All models feature a Broadcom system on a chip (SoC) with an integrated ARM compatible central processing unit (CPU) and on-chip graphics processing unit (GPU)
The Foundation provides Raspbian, a Debian-based Linux distribution for download, as well as third-party Ubuntu, Windows 10 IoT Core, RISC OS, and specialised media center distributions.
The Raspberry Pi 3 Model B+ is the latest product in the Raspberry Pi 3 range, a 64-bit quad core processor running at 1.4GHz, dual-band 2.4GHz and 5GHz wireless LAN, Bluetooth 4.2/BLE, faster Ethernet, and PoE capability via a separate PoE HAT The dual-band wireless LAN comes with modular compliance certification, allowing the board to be designed into end products with significantly reduced wireless LAN compliance testing, improving both cost and time to market. The Raspberry Pi 3 Model B+ maintains the same mechanical footprint as both the Raspberry Pi 2 Model B and the Raspberry Pi 3 Model B. Raspberry Pi 3 - Model B+
