by WALKSNAIL

Product Description

The Walksnail Ascent Lite Kit (Model: WN13-4S09B) is an ultra-lightweight digital HD video transmission system engineered by CaddxFPV as a cost-effective, high-performance digital entry point for micro FPV drones, 2 to 4-inch freestyle quads, and tinywhoops. Combining a 6-gram bare-board VTX with a micro nano-sized camera, the system delivers fluid 1080p video at 60fps and 720p at 100fps with an average latency of 35ms.

Designed for efficiency and low power draw, the Ascent Lite VTX features a 25 x 25 mm M2 mounting hole pattern, an operating input voltage range of 3.0V to 12.6V (1S to 3S LiPo), and up to 100mW (20dBm) of transmit power. The integrated nano camera features a 1/2.8-inch image sensor with an immersive 147-degree FOV in 16:9 aspect ratio. Complete Canvas mode OSD support across Betaflight, INAV, and ArduPilot ensures seamless flight telemetry overlay.

Key Features

• Ultralight 6g VTX Core: Compact 30.5 x 30.5 mm VTX board with a 25 x 25 mm M2 mounting pattern reduces weight for enhanced micro drone agility.

• High-Definition 1080p/60fps & 720p/100fps: Delivers clean HD video feeds with an average end-to-end latency of 35ms.

• Low Power Consumption: Consumes 30 percent less power than comparable VTX modules to extend flight times.

• 1/2.8-Inch Nano Camera: Compact 12 x 14 x 15 mm camera body featuring a wide 147-degree FOV lens in 16:9 format.

• Wide 1S to 3S LiPo Voltage Input: Accepts 3.0V to 12.6V DC input for direct powering from 1S, 2S, or 3S battery packs.

• Canvas Mode OSD Integration: Full flight telemetry OSD support for Betaflight, INAV, FETtec, KISS, and ArduPilot.
