How to Use TBS Crossfire on SBUS

I know what you’re thinking, why would you use the TBS Crossfire on SBUS protocol and not crossfire protocol?  Well sometimes you don’t have a choice.

I’ve been using the EMAX Mini Magnum 2 on all my Neutrons and love the stack.  It’s been super reliable but it doesn’t have any spare UARTS to connect a Crossfire Nano.  I didn’t think it was possible until a friend showed me.

Parts Used in this build:


The normal way to setup the TBS CrossfireNano RX is power, ground, channel 1 to RX/channel 2 to TX on a spare UART port. Of course that’s the preferred method if you have a spare UART port to use.

If you are using a flight controller like on the EMAX Mini Magnum 2 stack, there isn’t a spare UART port.  To setup the Crossfire Nano on SBUS is even easier, positive, ground, Channel1 on the Crossfire goes to SBUS on the flight controller, channel 2 isn’t used.

Crossfire Nano Setup

On the Crossfire Nano, set Channel 1 to SBUS

On the BetaFlight Ports, enable serial on the SBUS port and configurations, set receiver to SBUS.  Done!

To get RSSI to work, set the Crossfire Nano to output RSSI on Channel 12

In the configurations tab enable TELEMETRY (see image above).

Change RSSI Channel to AUX 8.  With the TX powered on and battery plugged in, you should see AUX 8 move around.  Enable RSSI in the OSD and you’ll see RSSI.  Done!

It’s nice to know that this option is available on the Crossfire Nano.  Even though you should use the Crossfire protocol if you can.

If you found this post helpful, it would be super cool if you purchased the components from my store or purchase items from my Amazon links.  These posts are expensive and take a loooong time to make so the purchases make it possible for me to keep making them.  Thanks in advance, I greatly appreciate it 🙂

    Daym. Didnt realise you couldnt use crossfire on the magnum 2. Thats a real shame. THey’ve missed a trick to making the perfect 20 x 20 stack

      i know! It needs 1 extra uart and m3 screw holes. Otherwise it’s perfect

    I’m using 900mhz tbs sbus on my foxeer r405 just because when I hook up crfx it shows pitch and roll moving at same time in reciever tab betaflight . On revolt v3 raceflight or betaflight. So switched to sbus protocol and all is well.. I can’t figure out why it’s doing this though with the nano rx. I’m dying figure out why. My older nano or full 8channel deversity reciever never had a problem Any help or input would be greatly appreciated

      what are your rx settings? you may have the channels mixed up
