Walksnail Ascent Pro VRX HD FPV Video Receiver
by WALKSNAIL

The Walksnail Ascent Pro VRX HD FPV Video Receiver (SKU: WN02-FP028) is an upgraded standalone digital HD receiver module engineered by CaddxFPV to output low-latency digital video to any HDMI-equipped FPV goggles, field monitors, or ground station displays. Stepping up from the standard Ascent receiver, the Pro model upgrades decoding capabilities to deliver Full HD 1080p at 120fps (as well as 1080p/100fps and 720p/120fps) with average end-to-end latency as low as 35ms.

Equipped with dual higher-gain 2.8dBi Red Bird Pro LHCP circular polarized antennas, active internal fan cooling, and adaptive frequency hopping, the Ascent Pro VRX achieves an extended transmission range of up to 8km. In addition to standard HDMI out and onboard 256GB MicroSD DVR recording, the Pro variant introduces direct UVC (USB Video Class) video output over USB Type-C for simultaneous streaming to compatible smartphones, tablets, or computers, alongside live synchronized audio transmission and Canvas Mode OSD support.

Key Features

• Full HD 1080p @ 120fps Decoding: Upgraded decoding architecture delivers high-definition 1080p video at up to 120fps for sharp visual fidelity and fluid motion tracking during high-speed racing and freestyle.

• Dual Display Output (HDMI & UVC Streaming): Features both a standard HDMI port for FPV goggles and monitors, plus a USB Type-C UVC video out interface to view, record, or livestream flight feeds directly on Android devices, tablets, and PCs.

• Extended 8km Digital Transmission: Paired with dual high-gain 2.8dBi Red Bird Pro antennas and auto-switching bandwidth (5MHz/10MHz/20MHz), expanding reliable range up to 8km.

• Active Cooling Fan System: An internal cooling fan and optimized airflow channels actively manage thermal levels to prevent frame drops or overheating during long sessions.

• Live Audio & Synced DVR Recording: Transmits real-time cockpit and motor audio over HDMI to display speakers and records synchronized audio and video tracks onto an onboard MicroSD card (up to 256GB).

• Full Canvas Mode OSD & Menu Recording: Supports native Betaflight, INAV, and ArduPilot telemetry overlays on-screen while offering direct recording of telemetry data directly onto DVR files.

• Wide 2S–6S Voltage Input: Accepts 7.4V to 25.2V DC input via a standard DC 5.5 x 2.1mm jack or SH1.0 6-pin header.
