News: Fatshark HDO2 FPV Goggles

Imagine Fatshark released a new goggles even before Orqa can get their FPV.ONE out of the door. Well, that might be happening! Fatshark just announced their next FPV goggles, the HDO2.

The Fatshark HDO2 is going to replace the HDO, and compete with Qrqa’s FPV.ONE and Skyzone’s SKY03O. Don’t forget to check out our FPV Goggles Buyers Guide to learn all the technical terms.

Probably not the complete list of features of the HDO2, but so far Fatshark has confirmed the following features:

  • Upgraded OLED screens
  • The revolutionary power button !
  • Adjustable focus
  • Integrated Fan Control
  • Adjustable Fit Faceplate
  • Supports 2S and 3S LiPo Input (7V – 13V)

Power button to turn the goggles on and off without unplugging the battery, which the users have been asking for years and Fatshark finally made it happen.

Adjustable focus to replace diopter lenses, designed for those who wear glasses, covering the +2 to -6 range.

Integrated fan control for adjusting fan speed level and switching the fan on and off with a button I presume. There is a DIY fan control mod for the older Fatshark goggles.

The HDO will come with the carrying case, lens cleaning cloth and a 2S 18650 case (same one you can buy from Fatshark).

The Fatshark HDO2 manual was leaked on the internet. From the manual we learned a lot more about the HDO2 specs and features.


  • FOV: 46°
  • IPD: 54mm – 74mm
  • Focus: +2 to -6
  • Aspect Ratio: 4:3 and 16:9 selectable
  • Resolution: 1280×960
  • Supports AV input and HDMI input
  • Supports Audio output
  • Input voltage: 7V-13V (2S/3S Li-)
  • Power Consumption: 320mA at 7.5V (no RX module), 770mA at 7.5V with Rapidfire
  • DVR supports SD cards up to 32GB
  • DVR record bit rate 6Mbps, MJPG compression, 30FPS, in AVI file format
  • DVR is upgradable via SD card
  • Dimension: 169.2x80x45.5mm

The OLED panels in the HDO2 has the same resolution as the ones in the Orqa FPV.ONE. I expect them to have matching performance, however we don’t know if they offer the same image quality at this stage yet.

Power Modes

The power modes might be confusing for some. According to the manual:

The HDO2 is shipped in Legacy Mode (like the HDO, HD3 and all older versions).

If you connect a battery to the HDO2, it will automatically power on and it will power off when the battery is removed. A short press of the Power Button will turn on and off the fan while in this mode. If you hold the button, the HDO2 will continuously beep to remind you the headset is in Legacy Mode and the goggles will not power down.

If you want, you can change the input power to use the Power Button to turn on and off the headset. To do this, you need to remove the Expansion Bay door and move the power mode jumper from Legacy Mode to Button Mode as show below.

While the headset is in Button Mode, a long press of the power button will turn on and off the goggles, while a short press will change the fan speed.

Note that Fan speed is proportional to the input voltage. If the headset is being powered from a 2S battery, maximum speed is recommended, and we recommend lowering fan speed if using a 3S battery. The low battery alarm also exhibits different behaviors for 2S and 3S. It is designed to work for 2S and may not provide much warning for 3S. We recommend not relying on the low battery indicator if you are using a 3S source as it will provide a very limited time window in which to return and land safely.

Here is the manual if you want to learn more:

Rumour is 4 to 5 weeks from today. Price is yet to be determined, my guess is it’s going to be around $600 given the higher specs and number of features compared to the HDO ($500).

I will come back to share more info.
