Need help wiring Frsky RX6R receiver to my flight controller.

[jakecrutherford]

I had trouble figuring out how to connect my RX via SBUS on my tyro 129 quad rotor kit, but I eventually found the SBUS pad that I needed to solder to. The morning after it was assembled, I noticed that my SBUS pad has completely separated from the flight controller completely. Would it be easier for me to try and repair/replace my SBUS pad, or would I be able to get a connection through one of my RX UART pads on the flight controller instead? Any help is greatly appreciated, as I am new to the RC hobby.

This is an issue with a lot of flight controllers where the pad comes off the board. You need a very small soldering iron to perform this type of sensitive soldering job. From your image there is still a little bit of track left but would require a professional soldering iron. Not sure if any other Uarts could be used as this depends on the FC.

I have the ability to repair the trace that is missing I was just hoping one of the UART pads on my flight controller would work so I would have an easy way out. If I could find out what kind of flight controller I have would anyone be able to tell me if there is a secondary connection I could use instead of my missing SBUS pad?
I will attempt replacing the missing trace and using solder paste for repair in the meantime but I look forward to hearing any other suggestions or tips from anyone.- I will update you all after I attempt the repair.

Repair is possibly the best, however if this connection break during flight it's game over. Using a UART may not be possible as the S-bus input gives you negative and positive going pulse configuration setup. The newer FC's mosly have holes in the pcb to stop this de-lamination issue.

Normally you would be able to configure a UART for Sbus, this is a VERY common use for many years. I do not know anything about your flight controller, you will have to do some research on that end of things.

this was all the information I could find about the flight controller so far. I see the TX2 pad can be used to configure smart port. Is that something I can do with my RX6R receiver?

 

[Wayne]

Yes, you have a Smart Port on your receiver.

Contact Eachine and ask them how to setup S.bus on this flight controller. Sure they will have an answer for you. Or contact the place that sold the thing.

Flight Controller I think is this one.

"- Plugs connector / Soldering Pads are Optional for all connector Port"

The white connector next to that pad is probably the same as the SBUS pad. Connect with the cable pictured and check in betaflight.

The image you have included is not for the RX6R connector as far as I can see. The RX6R has a 6 pin white connector and the picture you included appears to be a 3 or 4 pin type? The receiver came with two leads with 6 pin white connectors as well as a manual with wiring details, please consult this and then check with the FC suppler on how to configure it using one of the other uart ports.
