Holybro Micro OSD V2 — ATmega328P, MAX7456 Monochrome OSD, Arduino Bootloader, PAL/NTSC, for Pixhawk, PX4 & APM FPV UAV
The Holybro Micro OSD V2 is a compact on-screen display (OSD) module for FPV UAVs, built around the ATmega328P microcontroller (with Arduino bootloader) and the MAX7456 monochrome OSD chip. It overlays flight data from your Pixhawk, PX4, or APM flight controller onto your FPV video feed in real time. Supports both NTSC and PAL video formats (PAL selectable via solder jumper). Includes GH connector cables for direct integration with Holybro flight controllers.
Key Features
- ATmega328P with Arduino Bootloader — Reprogrammable via standard Arduino tools for custom OSD firmware
- MAX7456 Monochrome OSD Chip — Industry-standard OSD IC for reliable video overlay of flight telemetry data
- PAL/NTSC Support — NTSC by default; PAL selectable via onboard solder jumper
- Standard 6-Pin ISP Header — For firmware flashing and programming via standard ISP programmer
- HSYNC & LOS Test Points — Exposed test points for signal diagnostics and custom integration
- Compact & Lightweight — 17.5 × 35mm, 3g; fits easily in compact FPV airframes
- Pixhawk / PX4 / APM Compatible — Designed for use with Holybro and other Pixhawk-compatible flight controllers
- GH Connector Cables Included — GH 6P, 4P, and 3P cables included for direct plug-in to Holybro FC TELEM/OSD ports

Applications
- FPV UAV real-time telemetry overlay (altitude, speed, battery voltage, heading, etc.)
- Pixhawk / PX4 / APM FPV builds requiring OSD integration
- Custom OSD firmware development via Arduino IDE
Important Notes
- BAT+ is directly connected to VTx and Camera — ensure your VTx and camera can handle your battery voltage before connecting; exceeding the max voltage rating of your equipment may cause damage
- PAL video: bridge the PAL solder jumper on the board to enable PAL output
- Reprogrammable via Arduino IDE using the standard ISP header
