CrossFire CRSF is bi-directional protocol designed by Team Blacksheep (TBS) which is supported by all Spirit units except Spirit 1 and micro Spirit. It is for sending all channel data and telemetry at the same time. This mean that you do not have to connect anything else except 4 wires.
Based on original CRSF protocol new ELRS protocol was designed which is also fully supported by Spirit.

There are multiple receivers and satellites with CRSF/ELRS support.

== Wiring ==

'''RUD port''' - black '''-''', red '''+''' powering wires, green '''RX''' signal.

'''AIL pin''' - white '''TX''' signal (pin closer to the port label).

== Spirit Settings ==

Now you are ready to power up the unit. If your Power supply is not connected yet, we recommend to connect it to the AUX1, AUX2 and/or CH0 port.
Before you can utilize the CrossFire connection, it is important to set the '''CRSF/ELRS''' receiver type at the General tab of the software. Please start the Spirit Settings and change the receiver type as displayed on the photo.
Then save the settings (e.g. by ''CTRL+S'') or the ''Backup tab/Unit - Save'' and restart the unit.

== Throttle output ==

You can connect ESC or Throttle servo directly to the Spirit unit at '''(AUX/AUX1 port)'''.

== Radio Integration ==

Integration support is available from Spirit firmware version 3.7.4. Integration menu can be opened at the '''Crossfire configure''' menu.

=== Integration menu ===

#Press '''SYS''' button (if using RadioMaster radio).
#Enter '''ELRS Lua script''' > '''Other Devices''' / '''Crossfire configure''' menu depending on OpenTX/EdgeTX firmware.
#Look for '''Spirit FBL''' entry - entry should be available if wiring is correct.
#Enter the menu. When configuration is done, press the '''RTN''' button which will automatically save all changes.
