Raspberry Pi

The Raspberry Pi is a credit-card sized computer that can perform many of the functions of a desktop computer. It has a 700MHz processor, 512MB of RAM, HDMI and USB ports, and runs Linux-based operating systems from a microSD card. While less powerful than a laptop, the Raspberry Pi provides an inexpensive platform for learning programming through languages like Python and experimenting with electronics. It has found applications as a desktop computer, game console, web server, and more. Later versions of the Raspberry Pi, such as the Raspberry Pi 3, increased processing power while maintaining a low price point.

History • The Rasberry Pi is the work of the rasberry Pi foundation, a charitable organisation. • UK registered charity (No. 1129409), may 2009 • It’s supported by the University of Cambridge Computer Laboratory and tech firm Broadcomm
Kit Components • Essential: – Raspberry Pi board – Prepared Operating System SD Card – USB keyboard – Display (with HDMI, DVI, or Composite input) – Power Supply • Highly suggested extras include: – USB mouse – Internet connectivity - LAN cable – Powered USB Hub – Case
Features • Ultra low-cost (Model A US$25, Model B$35) cost between 1500 rs to 2500 rs • Ultra low power ~ 1W • Credit-card sized, fanless, instant start-up • Complete easy to program computer
Features • Provide a fun environment for experimenting with programming and electronics • Inexpensive, simple, open and easy to maintain computer for schools • Fun computer for children to experiment with at home(Programming, robotics etc)
Programming Languages • The Raspberry Pi Foundation recommends Python • Any language which will compile for ARMv6 can be used • Installed by default on the Raspberry Pi: – C – C++ – Java – Scratch – Ruby
Technology • The Rasberry Pi has a Broadcom BCM2835 system on a chip (SoC), which includes an ARM II 76jZF-S 700 Mhz processor • Video Core IV GPU • Originally shipped with 256MB of Ram • It does not include a built-in hard disk , but uses an SD card for booting and long-term storage
HARDWARE • 10/100 BaseT Ethernet socket • HDMI socket • USB 2.0 socket • RCA video socket • SD card socket • Powered from microUSB socket • 3.5 mm audio out jack • Header footprint for camera connection

DISADVANTAGE • It does not have a Hard Disk associated with it for a permanent storage of files, we have to connect one externally or have to use SD card for the purpose. • The RAM is a POP package on Top of the SoC, so its not removal or swappable. • There is no Real Time clock associated with the board. Adding an RTC is expensive. You can add one using the GPIO pins.
Rasberry Pi 2020 • Exploit process scaling and keep price constant • 8 cores, improved GPU, 8GB main memory • matchbox sized case • Holographic laser projector, virtual keyboard • FPGA logic on main SoC, high speed links,….. • <25$
