RASPBERRY PI 2, MODEL B产品概述
Raspberry Pi 2 Model B SBC
The Raspberry Pi 2, Model B delivers 6 times the processing capacity of previous models. This second generation Raspberry Pi has an upgraded Broadcom BCM2836 processor, which is a powerful ARM Cortex-A7 based quad-core processor that runs at 900MHz. The board also features an increase in memory capacity to 1Gbyte. Raspberry Pi is an Open-Source product designed to be supported by Internet-based user forums. As a starting point refer to the Official website at: http://www.raspberrypi.org/.
