+We used the following components to build up our client infrastructure. Note that links provided are just proposals for your convenience, other components will also work. Depending on your specific needs, there are several different methods to build and use your flarmradar groundstation. For all cases you need:
+
   - a FLARM device
-  - a [http://www.raspberrypi.org Raspberry PI] 
-  - Power supply:
-   - As Flarm is running on 12V and to ease use of a mobile flarmradar gound station powered by a 12V battery, we recommend a 12V power supply for the flarmradar ground station (FGS)
-    - Use a standard power converter (e.g. [http://de.rs-online.com/web/p/steckernetzteile/6666928/ RS-Online]) if an electical outlet is available to power the FGS
+  - a [http://www.raspberrypi.org Raspberry PI]
+
+
+    All revisions of the Pi can be used for Flarmradar ground stations. Depending on the revision you choose to use, wiring instructions differ slightly.
+  - a Power supply
+
+  Depending on your specific requirements, creativity, etc. there are a lot of different ways to supply your Flarmradar ground station with power. We gathered experience with a few ways and will describe the different setups below.
+  Flarm devices typically run on 12VDV power supply. All Raspberry Pi run on 5VDC. Hence you will have to generate and supply two different voltages within your ground station.
+
+      - Power supply from grid available
+       - Use two standard power converter (e.g. [http://de.rs-online.com/web/p/steckernetzteile/6666928/ RS-Online]) to supply 12VDC and 5VDC
     - For battery powered FGS, use a 12V battery as used in most gliders
     - To connect the FGS to external power supply or battery, use a connector, which is protected against polarity reversal (e.g. [http://de.rs-online.com/web/p/dc-buchsen/7684419/ RS-Online])
