+## FrSky telemetry
+
+FrSky telemetry signals are inverted.  To connect a cleanflight capable board to an FrSKy receiver you have some options.
+
+1. A hardware inverter - Built in to some flight controllers.
+2. Use software serial and enable frsky_inversion.
+3. Use a flight controller that has software configurable hardware inversion (e.g. STM32F30x).
+
+For 1, just connect your inverter to a usart or software serial port.
+For 2 and 3 use the cli command as follows:
+
+```
+set frsky_inversion = 1
+```
+
