The HolyBro Atlatl HV Micro Vtx is a power switchable video transmitter build to mount into a 20x20 stack. It can switch between 0.5 mW (pit mode), 25 mW, 200 mW, 500 mW, and 800 mW and has 2-6s LiPo power input.

Features

• Compatible with all major FPV receivers from vendors such as Fatshark, ImmersionRC, etc.
• Supports the standard 40-channel set: band A, B, E, Fatshark, and Raceband.
• SmartAudio input allows remote control by the flight controller. Change channel, transmit power, and more from Betaflight OSD, flight controller USB port, Taranis Lua Script, and more.
• All parameters are controllable via push-button on the side of the unit, for cases where SmartAudio is not used.
• MMCX connector is durable and easy to use. Rated for 100’s of mating cycles. Easy and quick antenna changes. No more ripped-off UFL connectors.
• LED indicators for channel, band, and power. Allows easy check of vTX parameters simply by glancing at the quad.
• Variable transmit power from 25 mW to 800 mW. Use 25 mW for a race and then easily switch to 800 mW for freestyle.
• 0.5 mW True Pit Mode allows you to power up safely without the risk of knocking other pilots out of the air.
• Built in microphone, so you can listen to your motors while you fly, no matter how far away you fly.
