The Raspberry Pi 2 Model B has “significantly upgraded” capabilities, with faster processor cores and a doubling in memory capacity to 1GB.
Raspberry Pi 2 incorporates the Broadcom BCM2836 application processor, containing an ARM Cortex-A7 quad-core CPU running at 800/900 MHz. This new processor makes the Raspberry Pi 2 more than six times more powerful than the first generation Raspberry Pi Model B+. The board layout, multimedia subsystem and peripherals remain fully compatible with the Raspberry Pi Model B+, including the use of the extensive 40-pin GPIO (General Purpose Input Output) connector, four USB ports and an efficient switching power supply. The board now hosts 1 GB of RAM, and boots in less than half the time of its predecessor.
All previous Raspberry Pi projects are compatible with the new Raspberry Pi 2 Model B, and the expanded GPIO pins, advanced power management and connectivity, make it possible to connect up to four USB devices, including some powered devices such as hard drives. The 40-pin GPIO enables multiple sensors, connectors and expansion boards to be added, with the first 26 pins identical to the Model A and B boards, for full backward compatibility.
element 14 notes that since its launch in February 2012 over four million Raspberry Pi boards have been sold and element14 adds that it has launched over 30 exclusive accessories specifically designed and manufactured to expand the usability of the Raspberry Pi for millions of customers worldwide. The distributor offers the element14 Community as a venue websites for discussion and collaboration around Raspberry Pi projects and developments.
RS cites its DesignSpark community and the range of free DesignSpark product-design software tools which it says are connecting students, users and engineers from many domains around the world.
