How-to
Set up your goggles in five minutes.
You need goggles with an ExpressLRS backpack (HDZero with the race-day firmware gets everything) and the bind phrase your radio uses.
What you need
Goggles with an ExpressLRS backpack, bound with the same bind phrase as your radio. HDZero goggles on the race-day firmware take Lowband channels and DVR names; stock firmware shows the OSD.
Add your bind phrase
Account → Goggles & OSD → ELRS Backpack. Type the phrase exactly as your radio has it (it's case- and space-sensitive). It's stored encrypted; after saving you'll only ever see it masked.
Check the binding ID
The page shows "Linked ✓" with the first and last byte of the binding ID. Your backpack's web UI shows the same UID: if they match, you're set.
Tell us about your goggles
Model, firmware (race-day or stock), versions and whether they're Lowband-ready, plus your preferred channel.
Lay out your screen
Open the screen editor and drag your readouts where you want them. The preview is what your goggles will show.
Enter a race day
When you're entered with a club, their timing laptop gets your binding ID and layout for that race day only.
Race
Power up when you're staged: your channel, OSD and DVR are handled for you.
If something's not right
- Nothing on screen: check the bind phrase matches your radio's exactly, and that the goggle backpack is on.
- No Lowband: it needs the race-day goggle firmware and Lowband-capable goggles. Tick Lowband-ready only if both are true.
- DVR stopped mid-race: that's why channels never change after a heat is armed.
- Wrong binding ID: re-enter the phrase. A stray space at the end changes the ID.
