BetaFPV M03 5.8G VTX

The BetaFPV M03 5.8G VTX is an ultra-lightweight, high-output analog video transmitter engineered specifically for 65mm to 85mm micro whoops and ultra-light long-range builds. Delivering a scalable transmission power ceiling up to 400mW, this VTX minimizes weight overhead while maintaining excellent signal penetration. When paired with an ExpressLRS control link, the M03 provides micro pilots with the range and video clarity needed to confidently explore larger flight boundaries.

Features

Micro Scale Power Scaling: Highly efficient adjustable output topology supporting PIT, 25mW, 100mW, 200mW, and a powerful 400mW maximum setting for extended analog video range.

Ultra-Light Structural Footprint: Shaves unnecessary bulk down to a mere 1.1 grams, ensuring minimal impact on micro quad center of gravity, flight times, and agility.

SmartAudio Parameter Control: Built-in SmartAudio protocol compatibility allows pilots to seamlessly adjust video channels, bands, and power levels directly via OSD or radio transmitter scripts.

Plug-and-Play Micro Camera Port: Features an onboard JST-0.8 connector configuration optimized for direct, tool-free installation with BetaFPV C01, C02, and NewBeeDrone BeeEye camera lines.

Broad Channel Spectrum Availability: Offers a complete 48-channel matrix across standard 5.8GHz bands, fully incorporating a highly stable Raceband frequency range for multi-pilot tracking.
