Hi all. I got an Oblivian which has Powercube and FPVision installed and I have the Crossfire Nano for my RX. I was wondering if there was a way to get RSSI thru the OSD using the Nano? I have tried turning chn 12 to LQ and RSSI and had no luck. If you guys have any suggestion I would appreciate it. Thanks
Try connecting the bst port to the bst port of the fpv layer (osd) layer, then there should be a setting on the osd for crossfire. If it's the same as the TBS cube on the Atom.

Should I just connect a wire from the BST SDA and BST SCL of the Nano to the bottom board of the power cube BST SDA and BST SCL pins? I can’t really find the pin layout for the FPVision OSD board which the BST port is at so I know what wires I need to remove from the harness that came with my Crossfire micro RX

http://www.team-blacksheep.com/tbs-crossfire-manual.pdf (page between 35 and 36 shows connecting to a powercube "Connecting CRSF from TBS CROSSFIRE RX to TBS POWERCUBE FC").
The page "Connecting CRSF from TBS CROSSFIRE RX to TBS POWERCUBE FC" statesBasically you already have ground connected so you should just need SCL to SCL, and SDA to SDA.BST cable to be able to getCORE PRO telemetry and control the OSD using the radio sticks.
That should do it.

Hi Steve Thanks for the help. I wired up my nano RX to my Oblivian using the UART1 port on top of the flight controller. Ground to ground 5volt to 5 volt chn1TX to UART1RX and chn2RX to UART1TX. I added the wires from the nano SCL and SDA pads to the bottom of the power cube BST port. I added picture to verify the routing of wires.

No I have not powered it up yet. Wanted to ask if I should put chn12 back to chn12 instead of LQ or RSSI in the tbs nano RX? And turn off RSSI in betaflight under receiver tab?
