Description

The Atlatl HV micro V2 is engineered for robust performance in demanding FPV environments. Its 30x26mm form factor integrates seamlessly onto standard 20x20mm flight controller stacks, minimizing wiring and maximizing build cleanliness. The unit supports the full 40-channel FPV spectrum including Raceband, ensuring compatibility with all major analog goggle receivers from FatShark, ImmersionRC, and others.

Built with a high-reliability MMCX connector, it eliminates the common failure point of fragile U.FL ports. An integrated microphone provides real-time audio feedback from your motors, enhancing situational awareness during flight. LED indicators on the board allow for quick visual confirmation of band, channel, and power settings without needing to connect to Betaflight.

Key Features

  • Wide 7-28V input range supports direct connection to 2S through 6S LiPo batteries without a separate BEC.
  • SmartAudio 2.0 protocol enables full control via Betaflight OSD, Taranis Lua scripts, or direct USB connection.
  • Manual push-button control allows parameter changes when SmartAudio is unavailable.
  • High-durability MMCX antenna connector prevents damage from frequent antenna swaps.
  • True Pit Mode reduces RF output to 0.5mW, allowing safe power-up in crowded race or event environments.
  • Built-in 6.5 MHz mono microphone for immersive flight audio.
  • Standard 20x20mm M3 mounting pattern with anti-vibration grommets for secure, clean installation.

Applications

  • 5-inch and 6-inch FPV racing drones requiring reliable, high-voltage video transmission.
  • Freestyle and long-range FPV builds where stable video signal across varying power levels is critical.
  • Micro and compact 3-inch builds where the 26mm width fits tightly integrated stacks.
  • Multi-rotor builds operating on 4S, 5S, or 6S LiPo batteries without a dedicated 5V/12V BEC for the VTX.
  • Drone racing events where quick pit mode activation and channel changes are necessary for compliance.

Frequently Asked Questions

What is the input voltage range for the Holybro Atlatl HV micro VTX?

The Atlatl HV micro accepts a wide input range from 7V to 28V, making it directly compatible with 2S, 3S, 4S, 5S, and 6S LiPo batteries without requiring a separate voltage regulator. This simplifies wiring and increases reliability in high-voltage power systems.

How do I control the VTX settings, and does it support Betaflight OSD?

The VTX is fully controllable via the SmartAudio 2.0 protocol. You can change the channel, band, and output power directly from the Betaflight OSD menu, via a Taranis Lua script, or through the flight controller's USB port. A manual push-button on the side of the unit provides backup control.

What is the advantage of the MMCX antenna connector over a U.FL connector?

The MMCX connector is significantly more durable and rated for hundreds of mating cycles, preventing the common issue of ripped or broken U.FL pads. It allows for quick and secure antenna changes, improving long-term reliability in crash-prone FPV applications.

What is True Pit Mode and when should I use it?

True Pit Mode reduces the RF output power to 0.5mW, allowing you to power on your drone on the bench or in a crowded race pit without interfering with other pilots' video signals. It's a safety feature required at most organized FPV racing events.

What is the mounting pattern and included hardware for installation?

The VTX uses a standard 20x20mm M3 mounting hole pattern, designed to stack directly on top of or below a 20x20mm flight controller. The package includes four M2 anti-vibration silicone grommets to isolate the board from frame vibrations.

Package Includes

  • 1 x Holybro Atlatl HV micro (VTX & OSD) Unit
  • 1 x 80mm SMA to MMCX Extension Cable
  • 1 x 60mm MMCX Antenna
  • 1 x 150mm 4-pin JST GH Wiring Harness
  • 4 x M2 Anti-Vibration Silicone Grommet Inserts
