how to hook it all up?

Former Member

hi all,

 

I am leaning toword the Model A but I still have some questions for which I doesn't see any answers.

 

1. what can a person not do with 256M of ram that a person with 512M of ram can do?

 

2. is it possible to connect a keyboard, mouse, monitor, ethernet, and hard drive to a Model A?

    with or without a hub?

 

3. is there a faster/more expensive version say with a quad core cpu/more ram in raspberry's future?

 

thanks to all,

charles.......

  • 1.  More ram means you can have more demanding applicatons running.  Such as games, 3D modelling, etc. It also gives you more speed in general because you are not writing to the swap file as much.

     

    2. No,  You will need a Model B for ethernet and connecting more than one USB device.

     

    3. No, the model B is the highest model avaiable ($10 more than Model A - there's your more expensive one image).

     

    If you want general setup information see this link:  http://www.raspberrypi.org/quick-start-guide

    thanks for the response,

     

    I was wodering if I get a usb hub with 7 ports and I hooked it up to the one usb port on the pi Model A, couldn't I just hook the rest of the usb stuff up to the hub and have it all work?  Has anyone even thought of this or tried it?

     

    yes I know the price of the hubs.

     

    thanks,

    Yes, that should work assuming that the hub has an external power jack with a good 5V supply.  The hub's upstream cable connects to RasPi model A's single full-size USB A port.  If the 7-port hub back-powers the upstream cable (which it's not supposed to do, but many hubs do it anyway) then the upstream cable can power your RasPi.  Otherwise, you can usually connect a USB A male to Micro USB B male cable between a one of the hub's 7 downstream ports and RasPi's power jack.  This way you only need a single power supply for everything.

     

    The USB cable powering RasPi should be as short as possible.  You can actually get a sizeable voltage drop across some Micro USB cables, in some cases enough to prevent RasPi from working reliably.
