BetaFPV C04 Camera with VTX module (Cetus X)

The BetaFPV C04 Camera and VTX Modular Assembly is an ultra-lightweight, high-resolution integrated video transmission subsystem engineered explicitly for seamless hot-swap deployment on the Cetus X micro FPV quadcopter. Stripping away complex custom wiring harnesses and mounting bracket friction points to achieve a combined physical mass of just 4.14 grams (including the linear dipole antenna), this true plug-and-play module stacks a sharp 1200TVL micro-sensor directly with an adjustable power analog video transmitter (VTX). Outfitted with an expanded 1/3-inch CMOS core and a wide-angle lens, it offers an immediate diagnostic or repair solution for field pilots, minimizing hangar downtime through modular component replacement.

Features

True Plug-and-Play Integration: Custom-engineered for drop-in mechanical and electrical convergence within the Cetus X canopy structure, eliminating manual soldering requirements through a fast-molded pin connector interface.

Integrated Space-Saving Core Architecture: Combines both the flight camera and the analog video transmission mainboard into a single heavily condensed structural block, maintaining micro airframe center-of-gravity targets.

Upgraded 1/3-Inch CMOS Imaging: Integrates an enlarged 1/3-inch CMOS sensor that captures high-density 1200TVL resolution combined with excellent low-latency response and balanced contrast shifting.

Ultra-Wide Panoramic Optics: Equipped with a premium wide-angle lens delivering a 160-degree horizontal field of view (FOV), providing exceptional peripheral awareness inside indoor flight paths or tight obstacle matrices.

Flexible VTX Transmission Profiles: Available in two distinct RF configurations tailored specifically to match your radio transmitter control link ecosystem, providing scaleable output power up to 450mW/350mW to optimize building penetration or field range.

Minimalist Structural Footprint: Adds a negligible 4.14 grams total weight including the high-flexibility antenna wire, ensuring flight agility, motor thermal efficiency, and overall throttle response remain uncompromised.

Operational Instructions

Airframe Disassembly Alignment: Power down the Cetus X completely. Remove the structural canopy fastening screws to lift the shield cowl away from the primary frame ducting, exposing the damaged video block.

Legacy Core Uncoupling: Carefully slide out the old camera/VTX assembly, pulling the multi-pin connector block straight out from the receiver socket on the flight controller mainboard.

Modular Insertion Execution: Align the pin array of the new C04 module (ensuring the wide-pin or short-pin layout perfectly matches your flight controller version). Slide the pin header firmly into the socket until fully seated.

Fastening and Reassembly: Position the C04 assembly into the canopy guide channels. Secure the structure utilizing the included factory screws (4 pieces for M04 version, 2 pieces for Cetus V2 version), route the linear antenna away from internal carbon lines, and reinstall the outer canopy.

Pre-Flight RF Validation: Turn on your FPV video goggles and connect a flight battery to the drone. Verify the 1200TVL video stream feed initializes instantly on the correct frequency channel, and inspect for visual interference or blackouts.

Notes

Strict Pin Variation Validation: Prior to executing installation loops, you must explicitly verify whether your Cetus X utilizes the wide-pin M04 VTX variant or the short-pin Cetus V2 version. Forcing a mismatched pin format into the flight controller receiving socket will instantly bend internal traces, destroy physical socket architecture, or bridge electrical lines causing terminal short circuits.

Avoid Raw Power Pitfalls: This integrated video transmission module is strictly engineered to operate from a regulated 5V power bus provided via the flight controller socket block. Do not attempt to run external high-voltage bridge lines directly from raw 2S–4S flight batteries, as doing so will bypass structural voltage limits and cause immediate, unrecoverable sensor component burnout.

VTX Thermal Heat Management Policy: Analog video transmitters running at elevated output profiles (350mW to 400mW) generate rapid localized heat build-up while sitting idle on the bench without cross-flow ventilation. Avoid leaving the battery connected on the ground for extended setup periods; calibrate settings quickly or utilize a portable field fan to prevent automated thermal shutdown or component degradation.
