TBS Crossfire Manual
Adapter boards
There are many ways of installing the Crossfire Rx into a model like these mounting boards:
On some of them you can connect a Unify Nano32 with the Crossfire receiver and use the CRSF connection
to control the VTx.
FrSky inverter mod
When you receive your Crossfire transmitter,there is a small inverter chip included. This chip is a hardware
mod that you can build into your FrSky radio to use the full communication speed between your radio and
the Crossfire Tx as some of them only have a slow transistor instead of an inverter chip included.
This mod is not necessary for the Crossfire to operate properly with your radio but it helps with “Sensor
lost” messages on certain radios as well as not properly working LUA scripts.
This modification requires a good soldering skill and will void your radios warranty. If you don’t feel
comfortable with this, use the software mod instead.
