DMKR 3.3G Custom Frequency Analog VRX Module

Overview

This 3.3GHz analog video receiver module is designed for embedded FPV systems requiring flexible frequency control and system-level integration.

With support for I2C communication and user-defined frequency configuration, the module enables direct control from flight controller or external MCU, making it suitable for OEM and ODM projects.

Custom Frequency and Control

The receiver supports frequency configuration via I2C interface, allowing external systems to define and control operating frequency programmatically.

Compared to fixed-channel receivers, this design enables:

• Flexible frequency allocation based on project requirements
• Integration with flight controller or custom control systems

RF Performance

The module operates within the 3.3GHz band and provides stable analog video reception with sensitivity around -95dBm.

Designed for consistent RF performance, it supports typical UAV video transmission systems and embedded FPV applications.

Power and Integration

The module operates on 5V input (4.5–5.5V recommended) and is optimized for integration into FPV goggles and embedded systems.
