Raspberry Pi is a Miniature Computer that can Interface with a Display Device like TV and a keyboard.

Raspberry Pi a teeny weeny Computer

Model A has been redesigned to have 256Mb RAM, one USB port and no Ethernet (network connection). Model B has 256Mb RAM, 2 USB port and an Ethernet port.

The Raspberry Pi measures 85.60mm x 53.98mm x 17mm, with a little overlap for the SD card and connectors which project over the edges. It weighs 45g.

The SoC is a Broadcom BCM2835. This contains an ARM1176JZFS, with floating point, running at 700Mhz, and a Videocore 4 GPU. The GPU is capable of BluRay quality playback, using H.264 at 40MBits/s. It has a fast 3D core accessed using the supplied OpenGL ES2.0 and OpenVG libraries.
Overall real world performance is something like a 300MHz Pentium 2, only with much, much swankier graphics.

There is composite and HDMI out on the board, so you can hook it up to an old analogue TV, to a digital TV or to a DVI monitor. No VGA support.

These are Tiny Chips that integrate the Microprocessor and Peripheral chips in a compact size with low power consumption. PIC Microcontrollers from Microchip are the evolved computing digital devices that go into many gadgets and intelligent equipment. These are easy to program and reprogram and even protect your code or IP.

The PIC has the math power. The memory, the I/O ports are integrated in the chip like 8051. Some may remember that Microprocessors like 8085 and Z80 had all these functions in chips outside and used to consume more power. Then came CMOS and better IC technology. The 8051(now avr, atmega)and PIC Micro are entire boards in one chip.

Starting with PICmicro controllers by Wouter van Ooijen. PICmicro is the brand name for a family of microcontrollers manufactured by Microchip. The PIC acronym stood for Peripheral Interface Controller, but recently Microchip has renamed their chips to PICmicro. Within this family the flash-microcontrollers (16×84, 16f62x, 16f87x) are ideal devices for hobbyists and low-volume professionals.

Learn to program in C with FED – This manual will take you through the process of learning C from variables through constants to pointers and then structures and unions. Most of the examples are standalone and are as small as possible to enable the purpose and effect to be easily understood.

PIC 18F4550 USB 16F877A IO RS232 Eval Board

The design is essentially a double evaluation board for the chips 18F4550 and 16F877A. It contains also a MAX232A serial module having two transmitters and two receivers with the ability to connect either to 4550 or 877 microcontroller. Each microcontroller port ends up to a pin header in order to give interconnection capabilities to the board for future experiments.
