I ordered some speedybee leds (2812-armlight) and they aren't turning on no matter what I do inside of Betaflight. I don't know if I am doing something wrong, or if they just don't work with the flight controller that I am using. All documentation I find uses the leds with the SpeedyBee FC, but the description on the product doesn't specify that it works with only one particular FC.
Help me :c

how do you have it wired up?

I have a 5v -> 5v / gnd -> gnd / led -> din
stuck mesa
Check on the FC if it's soldered for Betaflight lights and not Mamba lights

Ok that might be the issue, I didn't even know there was a difference

Not sure what FC you have but look at the wiring diagram

Just checked and it uses Betaflight LED, so you're good
Wiring is good too, so I'm pretty sure it's in Betaflight not setup properly

This guide might help you with your problem.

Ill check it out thanks :)

Do you think these wires are shorting?
This is my current Led config
It looks right?
stuck mesa
It's poorly done
mystic fable
Im gonna resolder it looks like
mystic fable
And use some flux
I dont have straight flux, I just use rosin core
should've thought about this a little more lol
I made it slightly better though I think

if you have vaseline that works, if you wanna do that. it’s weird but i’ve tried it and it hasn’t failed me yet
mystic fable
Still not the best solder job, but you can tell they’re on their own pad
I also soldered the wires onto the led to see if I was just having an issue with the connector
It still doesn’t work :(
mystic fable
I just tried trouble shooting the leds with the battery plugged in cause I saw JB do it that way and my drone started chirping at me and now my reaper VTX 2.5w isn't turning on...
uhhh
outer basin
is the vtx also on the 5v rail?
i doubt it but it might be a short somewhere along the line
outer basin
is the vtx also on the 5v rail?
if this is the case
mystic fable
it was on a 9v line
it got really hot
I had it plugged for like 7-10min while I was troubleshooting on betaflight
outer basin
yikes, do you know if it was in pit mode? or at least 25 mw? even still 7-10 mins is a while but it shouldn’t have killed it
outer basin
do you have another power supply to test it with? i recommend removing it to confirm it’s dead and also prevent any more damage. it might be shorting out your 9v power rail.
mystic fable
I have a second drone I can solder it to
might take a bit
feeling a little bummed
my status light is still green on the FC
for 9v
outer basin
that’s good then
but damn, those 2 watt vtxs are a pretty penny
it’s odd that it just died
mystic fable
I'd like to think its my bad solder job
It was always working fine in the past, I dont know why it would stop
but I'll redo it
ITS ON
I was on the verge of just laying on the floor and submitting lol
Ok lesson learned
low watt and pit mode
I can’t tell if it’s heating up faster
It’s also taking a few more seconds for it to turn on
Do you think its damaged at all?
outer basin
maybe but it’s hard to tell honestly. i mean if it works most likely damage is minimal but ay, lesson learned lmao
sometimes these vtx’s have built in safeties so if they overheat they stop working
mystic fable
I'll find out when I fly tomorrow, without leds probably haha
I set it to 25mw and it heats way less fast
gonna keep it on that or pit when I work on the bench for now on
was scary
outer basin
it is what it is, at least it still works lol
