Powercube FPVision

[Sam Richard]

Not yet, ordered two 3rd party GPS with I2C and UART, I hope they will arrive this week
The weird part is, the Crossfire TX shows GPS coordinates from a GPS, connected by UART directly to a Omnibus F4, which is again connected by CRSF and UART3 to a Crossfire Micro.
So in general, everything required is there. I just don't get it why the Crossfire Micro can take the information, but not the FPVision OSD. I guess this is above the usual OSI Layers, might be a Layer 8 Problem (financial layer)

I-Nav sens the GPS data via TLM to the X-Fire

but the Vision needs the TBS BST, like from the TBS GPS, also to access the Visions Settings you need a connection via BTS from the X-Fire RX

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

BST cable to be able to getCORE PRO telemetry and control the OSD using the radio sticks.

Basically you already have ground connected so you should just need SCL to SCL, and SDA to SDA.

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.

Here is the picture didn't load last time.

Looks correctly wired to me, is it working?

Here is what I get on my Atomv3 with BST connected:



It shows 10mw tx, 300% and -36db.

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?
