CAMLINK

Action cam telemetry in your Betaflight OSD

Live in your Betaflight OSD. GoPro, DJI, Sony, Blackmagic. How much each one sends differs, and the picker below shows yours.

The camera knows it stopped recording. You don't, until you land.

CAMLINK is a board that solders to a spare UART on your flight controller. Over Bluetooth it puts the camera's own status into your goggles: you see it recording, you see the clip running, you see battery and card before they run out.

Analog, HDZero, Walksnail, DJI: the video link doesn't matter. Betaflight 2025.12 or newer does.

You arm, the camera records. You disarm, it stops.

Your camera's record button is now optional.

Arm-records is the default, not the only mode: recording can sit on a switch or a button on your radio instead. Combi layers the button on top of the automation, and it's how we fly: arm starts the clip, a bad take gets cut and restarted from the button.

Set the exposure once, and the after-landing ritual of checking clip, battery and card has already happened in your goggles on the way home. Time at the spot goes into flying.

It's a passenger: CAMLINK sits outside the motor, PID and RC control paths, so it has no way to command the quad. If it loses the camera or hangs, your flight carries on unchanged.

Switch GoPro presets, mid-flight

Map up to three GoPro presets to one AUX channel. Cruise in 25 fps cinematic, flick to 200 for the trick, flick back. No landing.

Mission 1 Pro in PAL: 4K 200 fps cinematic to 1080p 800 fps burst, mid-pass.

Burst modes were unusable on a quad until now. The capture window is 7 to 15 seconds, so the clip was over before you ever reached the line: the only way to film 800 fps was pressing record with the subject already in front of the lens. Now you cruise out on a normal preset and flick to burst the moment the pass starts.

Preset switching is GoPro only.

GoPros stop forgetting the date

Naked GoPros lose their clock every time the battery comes out, and your footage ends up stamped 2016-01-01. Turn it on once in Setup, and on quads with GPS CAMLINK sets the camera clock from the FC's GPS time after connecting. No QR codes, no phone, no Quik app. GoPro only.

Pairs in seconds. Swap cameras just as fast.

CAMLINK holds one camera at a time, and it doesn't care which brand you point it at. GoPro on the long-range quad this weekend, DJI on the same quad the next, nothing rewired and nothing reconfigured in Betaflight.

Mission 1 Pro paired, then an Osmo Action 6. Same module, nothing rewired.

What your camera puts in your goggles

Every camera gives you the same core: what it's doing, how long it's been doing it, battery, and record time left. After that they differ, and the difference is the camera's, not ours. Pick yours and see the screen you'd actually get.

If your camera is not in the list, CAMLINK does not support it.

The greyed rows are deliberate. CAMLINK only ever shows what the camera actually reported: a value it can't confirm stays blank, because a wrong readout is worse than no readout. And if the camera stops answering, it says so. On a cold long-range flight that's the difference between knowing at minute ten and finding out at home.

Camera brands change their Bluetooth behaviour without telling anyone. What you're buying is what's on the tested list today. New cameras show up here when we get them working, and the module takes firmware updates.

Three quads, three modules

Most of us don't fly one quad. CAMLINK solders in permanently, so it lives on the frame you put it on. Every quad in the bag reports the same four lines, in the same place. Three for €149.99.

Installing it: about 30 minutes

Four wires, one free UART. If you've soldered a VTX in, you've done a harder job than this one. In Betaflight you enable MSP on that UART and switch on Custom Message 1 to 4. Where those four lines sit is yours to pick: one tap in Setup drops them top or bottom left, or you place them by hand in the Betaflight OSD tab.

Two ways to mount it. Shrink it straight into the frame and it disappears, but the buttons on the module get hard to reach. Or use the case, which is what we'd do: one mount clips to an it's FPV camera cage, the other takes a round 5 mm standoff, and both mounts are in the box. The cage itself is not. Either way, as close to the camera as you can get it.

Pair it and fly. The rest is optional.

Pairing is one press of the button on the module. No phone, no app, no page, nothing to type. Every boot after that finds the same camera on its own.

The four lines arrive carrying what matters: what the camera is doing and for how long, battery, record time left, resolution and frame rate. Recording on arm is already on. You can stop here and go fly.

Setup Mode is for when you want more, not because something is missing. CAMLINK serves its own page: hold the second button and it opens a Wi-Fi network, join it with your phone, type 10.0.0.1 in the browser.

Everything else lives there. Drag the OSD values wherever you want them, put GoPro presets or HiLight tags on a switch, turn on GPS clock sync, pick the warnings you want to see. Three ready layouts if you'd rather not decide, and a full editor if you would.

No app, no cable, no account. A page the module serves itself.

Don't buy one yet if

• Every UART on your FC is taken.
• You don't want to solder.
• You're on Betaflight 4.5 and staying there.
• The picker above shows your camera as untested and you need a guarantee.

What's in the box

• CAMLINK PCB with injection-molded polypropylene case in the color you picked
• Pre-cut clear heatshrink, if you'd rather shrink the board than case it
• 4-wire silicone harness (5 V, GND, TX, RX)
• Camera cage mount and standoff mount
• M2 screw
