The Raspberry Pi is a small SBC (Single Board Computer) perfect for learning programming or using as a small desktop PC. It supports both HDMI and composite video which makes it very versatile for both business and educational environments. The Raspberry Pi can do many tasks of the basic Office PC such as spreadsheets, word processing and working with videos.

Product Description

This Model B board incorporates 2 x USB ports, 512MB Onboard Memory, One Ethernet port as well as HDMI and Composite Video. There is also a SD card slot for loading the operating system.

The design is based around a Broadcom BCM2835 SoC, which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 256 Megabytes of RAM. This revision 2.0 board features two mounting holes for easy installation, a built-in reset circuit, and can be powered via the USB data ports. The design does not include a built-in hard disk or solid-state drive, instead relying on an SD card for booting and long-term storage. This board is intended to run Linux kernel based operating systems.

The Raspberry Pi use Linux-kernel based operating systems. Debian GNU/Linux, Iceweasel, Calligra Suite and Python are planned to be bundled with the Raspberry Pi. The Raspberry Pi does not come with a real-time clock, so an OS must use a network time server, or ask the user for time information at boot time to get access to time and date info for file time and date stamping. However a real time clock (such as the DS1307) with battery backup can be easily added via the I2C interface.

    There are several add-on boards developed exclusively for the Raspberry Pi to add additional support for peripherals
  • The Chipkit Pi adds 3.3V Arduino compatibility
  • The Pi Face adds relays and switches to power motors and sensors
  • The Embedded Pi adds both 3.3V and 5V Arduino compatibility
  • The Pi Rack is an expansion boards that supports up to 4 additional boards and adds the ability to power those boards independently

    I'm running the latest version of Rasbian Linux (Dabian derivitive) on the Raspberry Pi and it's pretty snappy. The graphical desktop works well and websurfing is pretty standard. The only drawback is no browser flash support. I like this thing so much I just ordered a ODROID -U2 quad core 1.7GHz Arm-9 board with 2GB ram to try something with more horsepower.

    I'm extremely happy with my purchase. This product met and even exceeded my expectations as far as picture quality and features go. I have Raspbmc hooked up to a 36 inch CRT standard definition TV via composite cable and the picture quality is really sharp and the colors are deep and vivid. I'm using a thick high quality composite cable, which helps with analog video signals though.

    I bought a Raspberry Pi Model B 512MB with which to play, and ended up with an HTPC running XBMC using OpenELEC. I am amazed at how beautifully it works! OpenELEC's XBMC plays everything flawlessly over nfs and smb. I haven't used wifi so I can't report on its capabilities. I have a couple of Boxee Boxes (disappointed with the company now) and they simply cannot compete with OpenELEC on RPi. I hooked the RPi up to a Samsung 46" SmartTV. Via HDMI-CEC, the Samsung TV's remote completely controls XBMC running on the Pi! And there's little things like having the XBMC remote app installed on my phone causes SMS messages to appear on the TV, and whatever I'm watching automatically pauses when I take a call; and, resumes with I terminate the call. There is not much more that I can wish to have in a HTPC. Anyway, dedicating my RPi as an HTPC resulted in me not having one for experimenting, so, I of course had to order another! Last year, I started teaching my sons digital electronics using Arduino. Adding RPi to our toolbox has given us all so many ideas for new gadgets. MCM Electronics seems to be a solid vendor. Their website is perfectly functional (as you probably already know) and they ship promptly and accurately. My only complaint is not with MCM Electronics at all, but rather with the Raspberry Pi Foundation's online store. This is where you purchase the licence keys for MPEG-2 and VC-1 codecs. The Raspberry Pi store promises to email you the licence key within 72 hours and... I'm still waiting on mine after 4 work-days. The only reason I ordered the MPEG-2 licence is because I hope it will solve the problem of the mythtv plugin not showing MPEG-2 video from live TV or recordings. The MythTV integration looks like it will be awesome... if I ever get my licence key emailed to me.

    I'm not sure why I waited so long to buy a Pi but I'm glad I finally did. This is a truly amazing device for anyone who likes to tinker. The possibilities are endless. I've been brushing up on my Linux skills and the Pi is a great help because I don't mind leaving it on all the time due to its low power consumption. Whatever I was working on is always right where I left it. But that's just the beginning. I've ordered the GPIO breakout kit so I can begin extending the Pi's functionality to external circuits. The combination of Linux and Python make the Pi a more accessible platform for this sort of tinkering than some of the others out there. I've been impressed by the Pi's performance so far. It is certainly limited but more than adequate for a multitude of uses that come to mind such as NAS, home automation, robotics, security, etc. For those getting started, I do think requirements for power and storage could be more clearly stated in the product details. The information is available but it requires a bit of research. Fortunately, I stumbled across it while pondering my purchase and have had no issues. It would be nice to have the ports arranged on one side of the board or at least at one corner but I understand why this was not done. It would also be nice if the GPIO interface had some built in protection to prevent damage when connection to external circuits. In conclusion, I really couldn't be happier with incredible value the Pi represents and I appreciate the efforts of those who worked so hard to develop it.

    The first I received the Raspberry Pi it was broken (sad face). Though I have no way of knowing if it was broken before shipping, the price vs. quality on the shipment leave something to be desired. The return process however was fast and efficient. The second Raspberry Pi works perfectly so far, though loading the SD card was slightly tedious (compatibility always my nemesis). After buying a compatible SD card, an entertaining task, going to misc. stores with a 20 page compatibility list and insisting that; "No not all SD cards play well with every thing else.". I got it up and running with XBMC, I have a new media server (happy face). There a few things could be better as fat as the component goes; better mounted RJ45 port, spring loaded SD slot, power button and though it would play havoc with PCB layout, it would be handy if all the ports were on the same side.

    I got my order in time (I was excited to order 3 units!). I put together the system and connected it to the HDMI TV. It seemed to work well, except for two major difficulties I faced. First, for some reason (no matter what keyboard layout I choose or not choose), it messes up the keyboard keys. When I chose the generic keyboard (104 or 101 keys), it seems to get two keys (and only two) incorrect: the @ and #. The latter shows up as British pound! The other difficulty I am having is in using the VNCserver to do remote access. It did work from to a degree remotely when I VNC into the Pi (which is running the tightvncserver). But the screen visible on the TV is different from what I see on the remote VNC session. No matter what widget I open remotely, the widget is not visible locally on the TV (and vice versa). The VNC screen is disjoint from what's on TV and defeats the purpose of a remote VNC to play (say a movie) on the TV connected to the Pi's HDMI port.

    Items arrived on time in perfect condition. I am happy to see that on these latest boards, the holes for P2 are not soldered over as they had been on my previous two boards from this merchant. That will make it easier for me to add my own pins to the holes for any projects which might need them. I would be happy to order again from this merchant and plan to do so in the future, as need arise.

    I was having all kinds of power problems with my Raspberry Pi. Did a little research and found out that you cant provide enough current to the Raspberry Pi through the micro USB connector. When I tried to hook up an external USB hard drive it would lock up. I found a power supply that doesn't use the micro USB connector. It uses the 26 pin connecter and provides up to 3 Amps @ 5 Volts. Wow what a difference, now I am running my external hard drive, keyboard, mouse and USB hub all powered from the USB ports on the Pi. Thanks rpips.com

    Great little low powered device but.... Plan your purchases and learn about the potential uses for the PI before ordering. If your household does not have a lot of network connected gadgets (and you like to tinker), you may want to buy more than one and save on shipping. I originally purchased the 256K B model to play with. When I used it to set up a NAS and my family suddenly needed a NAS up 24/7 – first PI gone. I purchased 2 more 512K B models from MCM and set up Xbian (just playing around) in the living room - now my family has confiscated that PI. I still have 1 PI to play with, but my daughter is eying that one as a media center for her room. It looks like I will be purchasing another PI in the near future.

    I already had an original 256MB Pi, and it worked so well I just had to buy a new 512MB version. While this works ok as a light duty web browsing system, and can play some games, it is not even close to replacing your home PC . Again, don't be surprised that this $35 computer can't do the same things as a normal PC that costs hundreds or thousands of dollars. My main use for the Rasberry Pi is running Raspbmc Media Center. I have a Windows Home Server that I access my media from and use my Android Phone and iPad with xbmcRemote on them as a remote control. If you've used an Xbox 360 or Playstation 3 as a media center, this will look familiar and works just as well. I'm happy knowing that due to its low cost that there are thousands of programmers out there writing awesome new programs and apps that I'll be able to use on this awesome little Gizmo.

    I purchased one of these from another distributor and loved it so much that I ordered 2 more from MCM. Running Raspbmc (XBMC) is exceptionally fast when installed on a flash drive and streams 1080p video perfectly from both my TB pocket drive (requires external hub, these don't put out a lot of amperage over the USB port) and my 4 TB NAS system. I'll now have one to experiment with using the GPIO pins, a dedicated XBMC front end, and another Pi to setup some automated options around the house. Easy to reflash if you break the kernel (happened to me twice) and the options for mounts / cases are limited only to what you can imagine. Heat sink kits are helpful if you're going to overclock them, but if not they aren't necessary. Low power requirements mean that you can run this from almost any USB power adapter including a decent filtered supply in my car. If you're using a powered USB Hub you will likely need to clip the power wire on the USB cable going from the hub to the Pi as it will feedback power through the USB ports causing potential problems and also ensuring that removing power from the Pi will become more difficult. I've been teaching my niece to program using Scratch and plan on ordering another board for her birthday so she can take it home with her.

    Quality:

    When using the Pi with MCMs 83-13110 wireless keyboard and mouse, the keyboard being right beside the Pi causes the mouse pointer to crash to the bottom of the screen shortly after booting to the OS desktop. This is caused by RF interference between the keyboard and Pi, placing the keyboard several feet away eliminates the crash. Other Pi users report a similar problem,its not a defective Pi, and not a defective keyboard, its RFI and anyone who buys this Pi must understand that it is NOT a finished Consumer product with a fancy plastic case and metal shielding will have to address possible RFI problems. This is an experimenters dream, its NOT a finished PC. Shielding the Pi might solve the problem. Other than that, it works great so far. Easy to configure, easy to flash the OS, the OS is similar to Windows. 4 Gb SD card 83-11233 This Pi has a cool factor of 100! Yes, it was the 512 version, that was worth the wait.
