Holybro Micro OSD V2
The Holybro Micro OSD V2 is a compact on-screen display module designed for UAV and multirotor systems, enabling real-time flight telemetry overlay on FPV video feeds. Professional drone pilots, FPV racing enthusiasts, and commercial UAV operators rely on this module to monitor critical flight parameters including altitude, speed, battery voltage, and GPS coordinates without breaking visual focus from their video stream. This module solves the critical problem of maintaining situational awareness during flight operations by seamlessly integrating telemetry data directly into the video transmission, eliminating the need for separate ground station monitoring equipment.
Product Overview
The Holybro Micro OSD V2 operates by intercepting the analog video signal from your flight camera and overlaying digital telemetry information in real-time using an integrated microprocessor. The module communicates with your flight controller via UART serial connection to receive live flight data, then composites this information onto the video signal before transmitting to your FPV receiver or recording device. This architecture ensures minimal latency addition to your video feed, critical for FPV racing and precision flight operations where even milliseconds of delay can impact performance.
What distinguishes the Micro OSD V2 from earlier generations is its enhanced processing capability, improved voltage regulation for stable operation across varying battery conditions, and optimized firmware that supports multiple flight controller platforms including Pixhawk, APM, and Betaflight ecosystems. The module features a compact form factor measuring just 36x36mm, making it ideal for weight-sensitive applications where every gram impacts flight time and responsiveness. Its robust design handles the vibration and thermal stress inherent in high-performance drone operations while maintaining consistent video quality and telemetry accuracy.

How to Use
Installation of the Holybro Micro OSD V2 requires three primary connections: video input from your flight camera, video output to your FPV transmitter or recording device, and serial UART connection to your flight controller. Begin by soldering the video input cable to your camera output, ensuring proper NTSC or PAL signal path. Next, connect the video output to your VTx transmitter or DVR device. The critical step is establishing the UART connection to your flight controller's telemetry port or designated serial port, typically using a 3-wire connection for TX, RX, and ground signals at 115200 baud rate.
After hardware installation, configure your flight controller to output telemetry data on the connected UART port. Most modern flight controllers require enabling the telemetry output in their configuration software. Power the system and verify video overlay appears correctly on your FPV monitor. Use your flight controller's ground station software or dedicated OSD configuration tools to customize which telemetry parameters display, their position on screen, and update frequency. Test all telemetry readings during a preflight check to confirm altitude, speed, battery voltage, and GPS data display accurately before conducting actual flight operations. Ensure proper heat dissipation by avoiding enclosure of the module and maintaining adequate airflow around the component during extended flight sessions.
Frequently Asked Questions
What video standards does the Holybro Micro OSD V2 support?
The Micro OSD V2 supports both NTSC and PAL analog composite video standards. The module automatically detects the incoming video standard and processes it accordingly. NTSC operates at 60 fields per second and is standard in North America and parts of Asia, while PAL operates at 50 fields per second and is used in Europe, Africa, and Australia. You can also manually configure the output standard through software settings if automatic detection requires adjustment for your specific equipment.
Which flight controllers are compatible with this OSD module?
The Holybro Micro OSD V2 maintains compatibility with Pixhawk, Pixhawk 2, APM 2.6, Betaflight, and Cleanflight flight controllers. Compatibility is achieved through standardized MAVLink and MSP protocol support over UART serial communication. The module requires a free serial port on your flight controller configured for telemetry output at 115200 baud rate. Some newer flight controllers may require firmware updates to ensure optimal telemetry streaming. Verify your specific flight controller model supports telemetry output before purchase if using specialized or legacy platforms.
Can I use the Micro OSD V2 with different battery voltage configurations?
Yes, the module's wide input voltage range of 5V to 17V DC supports single-cell through four-cell LiPo battery configurations. The integrated voltage regulator maintains stable operation across this entire range, eliminating the need for external step-down converters. This flexibility allows installation on racing drones using 1S batteries, medium-sized platforms with 2S or 3S batteries, and larger aerial systems using 4S configurations. However, ensure your power connection uses appropriate gauge wiring for your expected current draw, typically 2-3 amps maximum during normal operation.
What telemetry parameters can be displayed on the video overlay?
The Micro OSD V2 can display numerous telemetry parameters including altitude above ground level, altitude above sea level, airspeed, ground speed, heading direction, battery voltage, battery current draw, battery capacity remaining in milliamp-hours, GPS satellite count, GPS accuracy, latitude and longitude coordinates, flight mode, throttle percentage, and various attitude angles. The exact available parameters depend on your flight controller's telemetry output capabilities. You can customize which parameters display, their position on screen, font size, and update frequency through configuration software to create your ideal display layout.
How much latency does the OSD module add to the video signal?
The Holybro Micro OSD V2 introduces minimal latency, typically less than 5 milliseconds, due to its efficient real-time processing architecture. This latency addition is imperceptible during FPV flight operations and maintains the responsiveness required for racing and precision maneuvers. The low latency is achieved through dedicated video processing hardware and optimized firmware that avoids unnecessary buffering. For comparison, most FPV systems already experience 20-40ms latency from the transmitter and receiver, making the OSD module's contribution negligible in the overall system latency budget.
