     All revisions of the Pi can be used for Flarmradar ground stations. Depending on the revision you choose to use, wiring instructions differ slightly. We recommend a Raspberry Type B. You can purchase an SD card with the Pi's operating system pre-installed. For Pi+SD card [http://raspberrypi.rsdelivers.com/product/rs/pi-bsd/raspberry-pi-type-b-with-8gb-sd-card/7858654.aspx see here].

+For initial OS setup of your Pi, you will need a USB keyboard (mouse is optional but helps) and a screen which connects to Chinch-video signal or HDMI. Once your Pi is connected to the network, you can disconnect keyboard and screen and access it remotely via SSH.
   - a Power supply

        - Use an internal power converter, which can supply 12VDC and 5VDC. See [attachment:Flarmradar_GS3.png Schematic]
       - NO Power supply from grid available = battery power
-       - Use a 12V battery (e.g. [http://de.rs-online.com/web/p/bleiakkus/6603627/ RS-Online]) to power your Flarm and use a DC/DC converter to power your Pi. Make sure, efficiency of your DC/DC converter is high (e.g. XXX) so you don't drain your battery too fast.

Make sure you buy a DC/DC converter with high efficiency so you don't drain your battery too fast.
        - All in one power supply: The Mean Well power converter [http://www.meanwell.com/search/ADD-55/ADD-55-spec.pdf ADD-55A] offers 12V and 5V power output which can be run on standard power supply (88-264VAC) when available. If no power line is availble the device features a battery charger to which you will have to attach a 12V backup battery (e.g. [http://de.rs-online.com/web/p/bleiakkus/6603627/ RS-Online]). This battery will power the groundstation when disconnected from power grid. See [attachment:Flarmradar_GS2.png Schematic]
