Video receiver GEPRC RAD MINI 5.8G 1W VTX

The GEPRC RAD MINI 5.8G 1W VTX is a high-performance analog video transmitter engineered for tight multirotor builds and freestyle FPV platforms. Delivering 5 adjustable power stages up to a high-penetration 1000mW output ceiling, it guarantees exceptional signal propagation and robust link stability across short to medium-range flight boundaries. Housed inside a high-strength 6061 aluminum alloy structural casing, its unique design maximizes passive thermal dissipation while providing professional-grade impact resistance. Outfitted with a wide 7V to 28V voltage tolerance, an integrated microphone, and an active over-temperature protection loop, this VTX features a micro 20x20mm mounting layout and supports the standardized IRC Tramp protocol alongside three region-specific frequency tables for compliant global deployment.

Features

High-Output Power Scaling: Outfitted with 5 adjustable power steps capable of stepping from stealth PIT mode up to a powerful 1000mW (1W) maximum output, making it ideal for versatile environment adaptations.

6061 Aluminum Thermal Armor: Precision-milled metal chassis serves as a high-efficiency passive cooling heatsink while shielding internal circuits from high-impact mechanical stress.

IRC Tramp Telemetry Interface: Seamlessly integrates with standard IRC Tramp protocol fields, allowing pilots to modify video channels, bands, and power steps directly through the Betaflight OSD.

High-Acoustic Onboard Microphone: Features a built-in miniature microphone transmitting real-time motor and environmental audio telemetry straight to the pilot's audio receiver.

Intelligent Over-Heat Safety: Built-in temperature control monitoring actively safeguards internal processing circuits by throttling RF output stages if thermal safety thresholds are crossed to prevent high-temperature damage.

Regional Frequency Flexibility: Pre-configured with three distinct channel mapping options (Universal, FCC, and EU layouts) to comply with local RF regulations and licensing authorities.

Single-Button Interface Logic: Features a simplified physical control button paired with 3 bright LED diagnostic indicators for instantaneous, tool-free field adjustments.

Dedicated Camera Power Rail: Features a clean, regulated 5V output line designed specifically to supply clean power to onboard camera modules or small auxiliary cooling hardware.

Notes

Before use install the antenna. Running a high-power VTX without an antenna will cause instant, catastrophic damage to the RF amplifier stage.

Fly with constant airflow and in a well-ventilated environment to prevent overheating. Install an additional cooling fan if operating in confined bench spaces.

The 5V output is designed strictly for powering the FPV camera or small auxiliary fans. Never connect the main power supply or battery mainline to this 5V output line, as it will destroy the VTX circuitry.
