What is HDZero?
PUSH YOUR SKILLS TO THE LIMIT
HDZero offers industry-leading low latency, giving you more time to react and the best possible chance of hitting
that next gap. With its smooth, consistent FPV video feed, you’ll experience the same locked-in feeling you get
with analog video–but with the clarity of HD.
MAKE IT AN EVENT
HDZero supports the standard 5.8ghz video channels, meaning you can have up to 8 simultaneous pilots flying
either full-quality HDZero or analog video. When you’re ready to take a break and spectate, you can tune in to any
channel and view the pilot’s feed with no loss of quality, giving you the same feeling of being in the air yourself.
UPGRADE YOUR FLEET
From 1S whoops to long-range wings, HDZero offers a variety of VTX and camera options to suit every build. You
may even be able to use the gear you already have–the HDZero receiver will work with any FPV goggle with an
HDMI input. HDZero can grow with your needs and fit perfectly into your preferred FPV craft.
RAPIDLY EVOLVING SYSTEM
HDZero is rapidly evolving. Please always use the latest firmware that is located at www.hd-zero.com/document.

HDZero Whoop Video Transmitter
The HDZero Whoop VTX is a digital HD 720p 60fps video transmitter capable of delivering up to 200mw on 5.8GHz.
The power input range is 7V –26V (2S –6S). Though the Whoop VTX has an integrated surge protection circuit, a
large capacitor (450+uF) parallel with battery leads is mandatory to smooth the power supply of the whole quad.
It is highly recommended to use a BEC (8-12V) to power this VTX. The maximum 1A current will be drawn from
BEC.
This VTX is designed for low-speed whoop application. It is vulnerable to be damaged by crash due to: (1) the UFL
connector is easily peeled off due to no antenna retention, and (2) it doesn’t support soft mounting. Though the
VTX can be mounted on a racing and other high-speed quad, it is highly recommended to consider HDZero Race
(V1 or V2) for such cases.
This VTX does not support
Smart Audio.

HDZero Whoop Lite Video Transmitter
The HDZero Whoop lite VTX is a digital HD 720p 60fps video transmitter capable of delivering up to 200mw on
5.8GHz.
The power input range is 2.8V –13V (1S-3S).
-When it is powered by a 5V pad of FC/BEC, make sure that 5V has 1.5A current output.
-When it is powered by an 1S battery directly, note that a rapid throttle up may cause voltage drop below
to 2.8V instantly, and that will cause video drop.
-There is no need for an external capacitor when it connects with FC/BEC or 1S battery. However, it is
strongly suggested to put on capacitor when powered by a 3S battery.
This VTX has protection cases mounted on both sides. These metal cases are grounded, and to provide protection
from crash. They can be removed for tiny whoop quad which cares about every added gram.
This VTX includes M3/M2 gummies for soft mounting, and zip ties for antenna retention. Though the VTX can be
mounted on a racing and other high-speed quad, it is highly recommended to consider HDZero Race (V1 or V2) for
such cases.

Connection between Race V1 VTX and FC
There are 3 methods to connect the VTX and flight controller:
-Plug the included harness, cut the cables to
-appropriate length, and solder them on FC
-Use solder pads on the back of the connector
-For FCs having BEC and UART connector, install harness to the included PH2.0 connector (Shown
above), and connect the harness with FC without any soldering.
Warning: Check that pinout matches the FC pinout before installing to be safe if plugging directly.
Mounting an u.FL antenna or pigtail
There are 2 methods to mount antenna on VTX:
-Use included retention screws, nuts and plate;
-Use included zip-ties.

HDZero Race V2 Video Transmitter
The HDZero Race VTX is a digital HD 720p 60fps video transmitter capable of delivering up to 200mw on 5.8GHz. It
works with the Shark Byte RX5.1 goggle module to transmit video, and with a remote controller to wirelessly
control the parameters for the transmitter and camera.
The power input range is 7V –26V (2S –6S). Though the Race VTX has an integrated surge protection circuit, a
large capacitor (450+uF) parallel with battery leads is mandatory to smooth the power supply of the whole quad.

-Use included zip-ties.
Connecting MIPI cable
Use the included zip-tie to secure MIPI cable and
protect MIPI connector.
Notes:
-SA Pin is needed to connect with FC only when you decide to let FC fully controls VTX’s freq and
outputting power. Read Using SmartAudio section to setup VTX table, and etc. Note that VTX Menu
is not available for this case.
-If SA pin is not connected, VTX will use its own logic to control freq and outputting power. It has VTX
Menu to setup these parameters.

HDZero Freestyle Video Transmitter
The HDZero Freestyle VTX offers unprecedented range and performance for the HDZero 5.8GHz digital
FPV system. With its high maximum output power and robust construction, this VTX is perfect for
freestyle and long-range builds.
With a tested maximum range of more than 18 miles, the Freestyle VTX will transmit a digital FPV feed
as far as you’re willing to fly. Not interested in long range? You’ll also see better performance in urban
environments and around obstacles, with none of the color noise or multipath interference issues of
analog video.

The 1st batch of Freestyle VTX, supports 2S-4S, A BEC supporting 2S-6S is included.
The 2nd batch and later, supports 2S-6S, and the BEC is not included.
Important Notes:
●Do not directly power this VTX with a 5S/6S battery for the 1st batch.
oUse 2S-4S VBAT, or included BEC, or FC with built-in BEC
oThe Freestyle VTX consumes up to 15W. If it is connected with FC that has a built-in
BEC output, make sure the BEC can provide enough current. For example, if the BEC
provides 10V, it needs a minimum of 1.5A current output.
●Removing the heat sink is not recommended because it is part of the design.
●Rotate the antenna as shown above before detaching it to reduce the risk of peeling off the UFL
connector.
HDZero Freestyle VTX is compliant with FCC 47 CFR 97.215(c). It is limited to 25mW/200mW out of the
box, but it is capable of up to 1W if you have the required HAM radio license to use this power output.
Download the special firmware from www.hd-zero.com/document to enable higher RF output modes.
Here are the steps:
1. Download firmware Unlock_FreestyleVTX.zip.
2. Unzip it to the root directory of SD Card.
3. Use the VRX to flash this firmware to the VTX.
4. Power on the VTX, BLUE LED will flash 3 times after it is done. This step unlocks VTX.
5. Power the VTX off.
6. Unzip normal VTX firmware to the root directory of SD Card.
7. Use the VRX to flash this firmware to the VTX.
8. The higher RF output options will now be available.
Please note once the VTX is unlocked, there is no need to unlock it again when there is newer firmware
available.
