+====== Crazyradio PA ======
+The Crazyradio PA is a 2.4 GHz radio USB dongle with a power amplifier.
+Currently it's only used to communicate with the [[projects:crazyflie:index|Crazyflie Nano Quadcopter]] but it can be adopted to work with a number of applications that are based on the low-cost 2.4 GHz chips from [[http://www.nordicsemi.com|Nordic Semiconductor]].
+====== Features ======
+  * Radio power amplifier giving 20dBm output power
+  * > 1km range LOS with Crazyflie 2.0
+  * 2x5 2.54mm header for prototyping (not mounted)
+  * Hardware support for PPM
+  * Same mechanical footprint as the first generation Crazyradio
+  * Open source firmware
+  * Firmware upgrade via USB
+  * Low latency
+====== User guide ======
+  * [[doc:crazyradio:install_windows_zadig|Install Crazyradio driver on Windows XP to 8]] (This is now the recomended procedure)
+  * [[projects:crazyradio:programming|Firmware upgrade]]
