Oh yeah. That’s bad

#

Does not look like any bridging, 🤔

#

white rx and gray is tx

#

and you connect it to opposites on the FC

#

so rx wire on the receiver connects to TX on the fc

#

and tx to rx

subtle atlas May 11, 2023, 1:49 AM

#

basically
TX on FC > RX on Reciever
RX on FC > TX on Reciever

#

also your leaving alot of exposed wire, they could short

wise aurora May 11, 2023, 1:49 AM

#

we need to see the section where it gets connected to the fc

subtle atlas May 11, 2023, 1:51 AM

#

so its a connector

wise aurora May 11, 2023, 1:51 AM

#

the connector is prob wired wrong

subtle atlas May 11, 2023, 1:52 AM

#

can you tell uss the FC so we can look at the diagram?

wise aurora May 11, 2023, 1:52 AM

#

thats the issue w connectors

#

and yea we going to need fc name

subtle atlas May 11, 2023, 1:53 AM

#

if it was a VTX plug and you put 12v in a 5v then that would do it

#

...

#

Im pretty sure you connected a 5v reciever to 25v

#

that would def do it

#

better pic

wise aurora May 11, 2023, 1:57 AM

#

lmao

#

thats kinda sad

#

thats video isnt it?

subtle atlas May 11, 2023, 1:57 AM

#

yea the battery is usually used for VTX, not a tiny lil RX

wise aurora May 11, 2023, 1:57 AM

#

you kinda fucked that up mate

subtle atlas May 11, 2023, 1:58 AM

#

next time you burn something and have a spare, maybe ask for help before powering up the second one

#

that is a rip tho

wise aurora May 11, 2023, 2:01 AM

#

non

#

you solder it

subtle atlas May 11, 2023, 2:01 AM

#

the FC is meant to be all plugs (pain)

wise aurora May 11, 2023, 2:01 AM

#

oh

#

i havent looked at the fc

#

im just assuming that its soldering required cuz its a plug in

subtle atlas May 11, 2023, 2:01 AM

#

well not all plugs, it just is mostly plugs to be "easier"

#

1 sec

#

the lighter gray is white but it would blend with the background

#

same connector, just move the wires to where I said

#

what

#

The RX connector not VTX

#

yea thats what did it

#

1 sec

#

#

also when unplugging connectors, pull on the connector itself not the wires

subtle atlas

Bro drew a whole ass diogram

subtle atlas May 11, 2023, 2:52 AM

#

yea

warm sandal May 12, 2023, 12:04 AM

#

Alright. Correct me if I'm wrong, but it looks like you're plugging the RX into a port that isn't specifically for the RX. You'll see it's the smaller one here, not the larger one for your O3 air unit.

#

I can't tell what's plugged in here, unfortunately.

#

But I believe it's for the RX.

subtle atlas May 12, 2023, 1:18 AM

#

warm sandal Alright. Correct me if I'm wrong, but it looks like you're plugging the RX into ...

yea they said they plugged it into the VTX port, meaning they put 25v into a 5v RX

warm sandal May 12, 2023, 1:22 AM

#

Yes, but I don't see anyone saying to use the small RX port and I'm curious why

#

It's what the docs specify to use

#

What's doubly curious is there's already something in that port

subtle atlas May 12, 2023, 1:23 AM

#

yea, its easier to solder it on the pad tho

warm sandal May 12, 2023, 2:14 AM

#

Is this the ideal solution for this user though?

#

As far as I know, iFlight will supply plugs for all types of receivers, including CRSF.

#

If this user has a CRSF plug, the ELRS receiver would be risk free plug and play.

#

Plus, what is currently in the RX port? I would like to know, in order to better formulate an answer.

warm sandal May 12, 2023, 9:17 PM

#

Huh? The air unit's plugged in to the little port?

#

And it's powering on?!

#

That port should be at most 5V, and is usually for the receiver

#

Interesting

#

Is this how the Evoque is usually wired up?

#

Like is this how it came?

#

I don't know enough about the platform. I'll look into it later.
