  • 1080p 90hz adaptive refresh rate OLED micro-displays
  • Wide field of view up to 46 degrees in 16:9 and 38degrees in 4:3
  • Resolutions for different flying types: 1080p30, 720p60, 540p90, and 540p60
  • Smoothest and fastest link for the most connected flying feel (3ms glass-to-glass)
  • Fly with friends – 1-way broadcast doesn’t interfere with nearby pilots
  • Improved analog video resolution with real-time deinterlacer
  • All the video input and output you need – one goggle for digital, analog, and HDMI video
    • Analog 3.5mm AV input
    • HDMI input and output (yes, it is possible to have both)
    • Headphone/microphone combo jack
  • Add-on Analog Module Bay with 2.4Ghz Wi-Fi module for future expansion:
    • Video streaming to phone (possible future capability)
    • OTA Goggle FW updates (possible future capability)
  • Mount antennas to innovative rail mount system


  • On/off sliding switch – be confident that the goggle is on or off at a glance or by feel
  • Designed for open source, the new goggle runs Linux. All code for the user interface is new and open source
  • Support diopter lens inserts
  • 90Hz 1080p OLED screens with sliding IPD adjustment and dials for focus adjustment
  • By integrating the entire goggle display pipeline with HDZero’s fixed-latency video transmission, these goggles achieve 3ms glass-to-glass sub-frame latency with no jitter or dropped frames
  • Mounting rails for patch antennas or whatever else you might want to mount
  • Recessed front SMA jacks so no need to remove antennas when packing the goggle away
  • Three independently addressable fans work in combination to cool the internals and prevent fogging. They are soft mounted to prevent screen vibration and noise

Repairs & Diagnostics

Power/Dead Goggles

Protection fuse and diode located on RH IO PCB on rear under the RH RF PCB.

Fuse in yellow box can go open circuit.

Referenced on HDZero Discord as fuse part number : CFS12V3T4R0

Poor Signal Or Loose SMA

SMA can break free from PCB if knocked or damaged. Can damage PCB tracks on earth and RF Input at point of contact Check track very closely at solder point.

HDZero Goggle Reboot With Crossfire/ ELRS 868 & 900Mhz

HDZero Goggles can reboot if you bring 900Mhz or 868Mhz RC system either next to the goggles or the power cable. Repair 1 – To prevent reboot via power cable install ferrite bead around power cable where it enters goggles, this will stop reboots when you bring RC close cable. Repair 2 – To prevent reboot happening even when close to the goggles Install 0.1uf capacitor either across power switch or on RH RF PCB as Shown
