Raspberry Pi Model B
First up on the SBC roundup is none other than the Raspberry Pi. This credit-card-sized device was originally developed by the Raspberry Pi Foundation (UK) to promote a simple and cost effective way of teaching basic computer science concepts in schools. Since its inception, the Linux-based Pi has become the foundation of several DIY project builds for mobile PC applications. These include projects such as pocket-sized media streaming, LED display boards, environmental sensing devices, Pi-powered cat feeders, and many more.
The Raspberry Pi Model B is based on the Broadcom BCM2835 SoC, equipped with an ARM11767JZF-S 700 MHz processor. As an upgrade to the original design, the Model B has 512 MB RAM with two USB ports and an Ethernet port. The VideoCore IV GPU enables high-definition video playback; I2C interface allows for device expansion; and an SD card slot is provided for booting and long-term memory storage.
Latest editions of the board feature firmware that lets the user "overclock" the processor. From the standard 700 MHz CPU / 250 MHz GFX core / 400 MHz SDRAM, the "Turbo" firmware can take the CPU up to 1,000 MHz CPU / 500 MHz core / 600 MHz SDRAM. This makes for a more pleasurable experience navigating the many operating systems the Raspberry Pi supports. Debian Linux and its derivative Raspbian OS being the most popular. The rest of the supported OS platforms being Android (2.3 & 4.0), Haiku, Firefox OS, Gentoo Linux, Google Chromium OS, Open web OS, Arch Linux ARM, Fedora, Plan 9, Slackware Linux, FreeBSD, NetBSD, and the RISC OS. The RISC OS only supported by later versions of the Raspberry Pi (v 5.17 and beyond).
Since its original release in August 2011, Raspberry Pi has gained a following of rabid developers. Despite its aging specifications, the Raspberry Pi's community is unmatched -- making the little board analogous with all SBC.
