Mini OSD for Pixhawk Flight Controller

The Mini OSD is a compact on-screen display module designed for Pixhawk flight controllers that overlays critical flight telemetry data directly onto FPV video feeds in real-time. Professional drone pilots, aerial photographers, and UAV system integrators rely on this module to monitor altitude, airspeed, battery voltage, GPS status, and flight mode without breaking visual contact with their aircraft. This module solves the critical problem of flight data visibility during FPV operations, enabling safer autonomous missions and manual flight control with complete situational awareness.

Product Overview

The Mini OSD operates as a dedicated video processor that intercepts the analog video signal from your FPV camera and intelligently overlays MAVLink telemetry data from the Pixhawk autopilot. The module uses a high-speed ARM processor to decode flight controller data via serial connection while simultaneously processing the video stream at 30fps with minimal latency. This real-time processing capability ensures pilots receive instantaneous feedback on critical parameters including heading, altitude AGL, ground speed, battery remaining percentage, and current draw, all composited onto the video feed with professional-grade clarity and minimal visual obstruction.

What distinguishes this Mini OSD variant is its compact form factor optimized for weight-sensitive applications like quadcopters and fixed-wing UAVs, combined with robust noise filtering for clean video output even in electromagnetically noisy environments. The module features onboard voltage regulation supporting 5V to 36V input from your power distribution board, eliminating the need for separate power conditioning. Its intelligent overlay engine allows customization of displayed parameters, screen position, and font sizes through ground station software, making it adaptable to various mission profiles from precision agriculture to infrastructure inspection.

• Educational and Research Applications: Telemetry visualization supports student learning of flight dynamics and enables researchers to correlate sensor data with video footage for post-flight analysis

How to Use

Installation begins with connecting the Mini OSD between your FPV camera and video transmitter using standard composite video connectors. The module requires three connections to your Pixhawk flight controller: power from any 5V-36V source on your power distribution board, ground connection, and a dedicated UART serial line configured for MAVLink protocol at 57600 baud. Most Pixhawk systems have dedicated telemetry ports that can be configured for OSD use through ArduPilot or PX4 firmware parameters. Once powered, the module initializes with default telemetry overlay and begins processing video immediately.

Configuration is accomplished through your ground station software such as Mission Planner or QGroundControl, where you can select which flight parameters to display, adjust overlay position and transparency, and customize font sizes based on your FPV monitor resolution. Test your setup on the ground with the aircraft powered on to verify telemetry data is flowing correctly and video quality is acceptable before flight operations. During flight, monitor the overlay for any signs of video corruption which would indicate improper shielding or power supply noise requiring additional filtering. Post-flight, review the recorded video to correlate telemetry data with flight behavior for mission analysis and system optimization.

Frequently Asked Questions

Is the Mini OSD compatible with all Pixhawk flight controllers?

The Mini OSD is compatible with Pixhawk 1, Pixhawk 2, Pixhawk 4, and other autopilots running ArduPilot or PX4 firmware that support MAVLink telemetry output via UART. Ensure your flight controller has an available serial port configured for telemetry output. Some autopilots may require firmware parameter adjustments to enable OSD serial communication.

What video format does this OSD support?

The Mini OSD processes standard NTSC or PAL composite analog video signals commonly used in FPV systems. It automatically detects the incoming video format and applies appropriate overlay scaling. The module does not support digital video formats like HDMI or USB video.

Can I use this OSD with non-Pixhawk autopilots?

The Mini OSD is specifically designed for Pixhawk flight controllers using MAVLink protocol. While some compatible autopilots like ArduPilot-based systems may work, we recommend confirming MAVLink compatibility before purchase. Non-Pixhawk systems would require custom firmware modifications.

What is the video latency introduced by this module?

The Mini OSD introduces approximately 50-100 milliseconds of latency in the video processing pipeline, which is imperceptible for most FPV applications. This latency is significantly lower than digital transmission systems and acceptable for real-time flight control feedback.

How do I troubleshoot if telemetry data is not appearing on screen?

First verify the serial connection between flight controller and OSD is secure and configured for 57600 baud in firmware settings. Check that MAVLink telemetry output is enabled on the flight controller. Ensure proper power supply voltage is reaching the OSD module. Test with a different UART port if available. If issues persist, contact our technical support team with your flight controller model and firmware version.
