Thoughts on UARTs (Telemetry & VTx OSD)
#1
So quick homework check as I wait for my last few parts to come in. I've intentionally decided to make this build a little more technical and complicated.

I am going to try to hook up smartport telemetry and an external OSD (through my VTx) on my current build. With USB and Rx that means I have 1 more device than UARTs in theory...

So I know that when folks use the F1 controllers they shared the USB UART for extra communication like telemetry.

My thoughts:

Wire OSD to UART1, Smartport to UART2, and Rx to UART3, making sure that OSD is unpluggable when hooking up to USB?

Or... interestingly enough... there is a USB port on the VTX... does this mean I may be able to hook up to my FC though a passthrough on the VTx? I have a similar setup on the GT2 so I may give it a try.

Can someone check to make sure that all my assumptions above are correct? Obviously I'll be able to test most of this once I get the parts in but a certain amount of this will require soldering so I'd like to be sure I at least am sort of thinking correct before I get started on that stuff.

Parts involved (in case it's relevant to my question... note: 2 of the 3 are different from the previous plan in my build thread)

Have you flashed the xsr with the latest firmware? There has been some improvements regarding telemetry recently

No worries on this build. What would I do is to plug the OSD on UART1 to share it with USB. Because OSD/VTX is not being powered on without a battery plugged in, this way you can:
Plug the USB to FC to configure the craft without issues (OSD is powered down)
Plug the USB to VTX to configure OSD without issues (FC is powered down)
You cannot flash/configure ESCs because you need to plug the battery in - even in this case it is pretty easy to just unplug one of the connectors.
Find me on Youtube and Instagram. I currently fly: DRC Aura, NOX5R, Minimalist 112 and drive a scrap RC car

Not yet, but I will be flashing it. I recently read about the upgrades and how to flash them

This is a great point, I didn't think about that. I can just make sure my ESCs are up to date when I am doing the build and then leave them be until there is something worth flashing for.
