I am trying to connect my x8R receiver to my Quad with Flip32 Rev6 board.

Followed the instructions to connect signal lead to 4th channel of the board which act as UART2, and changed settings in cleanflight accordingly. But still I couldn't connect successfully. Am I missing something?

Gone through many threads but still not successful. Some says inverted signal cable can make it work, and some says its not required.
Can anyone guide me?

Signal Inversion is required to run sbus.

Something like this

Yeah, precisely! Do not buy the Frsky inverter.  You can build it for a fraction of the price!

Seen this already, just want to re-assure if this can work without the inverted cable.
I will try this.

Got the inverted wire soldered, its working now. Total cost just 5rs.

Thank you all
