Description

The ReadyToSky L-C Power Filter is engineered to solve a common issue in FPV builds: video interference caused by electrical noise on the power rail. By employing a dedicated LC (inductor-capacitor) circuit, it filters out high-frequency ripple and jitter from the main battery or BEC supply, providing a clean, stable DC output for your video transmitter. This results in a dramatically cleaner video feed free of rolling lines or static.

Its design prioritizes integration ease with an exceptionally small form factor and minimal weight, making it suitable for even the most space-constrained micro and whoop builds. The inclusion of reverse polarity protection adds a layer of safety during installation, preventing accidental damage from incorrect wiring. The filter’s low voltage drop ensures your VTX receives consistent voltage, maintaining optimal transmission power and signal integrity.

Key Features

LC Filter Circuitry: Utilizes an inductor and capacitor to attenuate high-frequency electrical noise from the power source.
1A Continuous Current Rating: Suitable for powering most analog and digital FPV video transmitters.
1-4S LiPo Input Range: Compatible with a wide spectrum of multirotor power systems from 1S micro drones to 4S freestyle rigs.
Reverse Polarity Protection: Integrated circuitry prevents damage if input wires are connected incorrectly.
Minimal Voltage Drop: Ensures the connected VTX receives nearly the full input voltage for consistent performance.
Ultra-Compact Design: Measures just 10mm x 4mm with a weight of approximately 1 gram.
Pre-attached Wiring: Includes connecting wires for simplified soldering and installation.

Applications

Cleaning power for analog VTXs on micro and whoop drones to eliminate motor-induced video noise.
Providing stable power to digital HD FPV systems (e.g., CaddxFPV, DJI, Walksnail Air Units) for reliable video transmission.
Integrating into 3-inch to 5-inch FPV racing and freestyle quadcopters where electrical noise is prevalent.
Use in long-range fixed-wing or rover builds to ensure clean video feed from the onboard VTX.

Frequently Asked Questions

What is the purpose of this LC Power Filter?

This LC Power Filter is designed to remove electrical noise (ripple and jitter) from the DC power supply of an FPV video transmitter. This noise, often caused by motors and ESCs, manifests as lines or static in your video feed. The filter provides a clean, stable voltage to the VTX, resulting in a clear, interference-free video signal.

Can I use this filter with a 6S LiPo battery?

No, this filter is rated for a maximum input voltage of 16V, which corresponds to a fully charged 4S LiPo (4 * 4.2V = 16.8V). Applying a 6S voltage (up to 25.2V) would exceed its maximum rating and likely damage the filter and potentially your connected video transmitter.

How do I wire the LC Power Filter into my FPV drone?

Connect the filter's INPUT wires to your drone's main power source (e.g., a regulated 5V/9V BEC or directly from the battery for analog VTXs). Connect the filter's OUTPUT wires to the power input pads of your video transmitter. Ensure correct polarity, as indicated on the filter board. The built-in reverse polarity protection offers safety against wiring mistakes.
