Raspberry Pi upgraded (512MB RAM)

I've had the pleasure in owning the first version of the Raspberry Pi and really liked it but for my media center idea it didn't work as smoothly as I wanted so I ended up selling it.  This version will help some of the shortfall of the low memory.  They have gone from 256MB to 512MB of ram now.  Some other nice features listed below: 

  • Broadcom BCM2835 700MHz ARM1176JZFS processor with FPU and Videocore 4 GPU
  • GPU provides Open GL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode, GPU is capable of 1Gpixel/s, 1.5Gtexel/s or 24GFLOPs with texture filtering and DMA infrastructure
  • 512MB RAM

This is a revision B board and has the audio connector already on it, that was another thing I was missing on the one I purchased.  This will make a awesome carputer, linux server, etc.  Now if your going to purchase one of these there are some things you should know first:

All you get is the board so you will need a power supply, sd card (class 10+), a keyboard & mouse.  I had issues with my keyboard and mouse so you may also need a powered usb hub to make them work better.   Here are the products I used:

  • 5v Power supply from a old cell phone, it requires 700ma but if you need one I highly suggest this
  • SD Card 4GB or better, i used this SanDisk Ultra 16 GB SDHC Class 6 Flash Memory Card 30MB/s SDSDH-016G-U46
  • As for a keyboard and mouse, i found that my cheap keyboard from Walmart didn't work so I had to purchase a powered usb hub then it worked fine.  It has to do with the power consumption of the usb devices and the Pi being limited in how much usb power it has.
