Mini OSD Board for APM — FPV Telemetry Overlay 📺

The Mini OSD is a compact on-screen display module that extracts telemetry from your APM or Pixhawk flight controller and overlays it onto your FPV video. Ideal for FPV flying and field use without a laptop, it lets you monitor critical flight data directly in your video feed. Screen layout and data fields are configurable; an FTDI adapter is required to program the OSD module (supported via the built-in Arduino bootloader).

Why choose this Mini OSD? ✈️

• Real-time telemetry overlay for FPV drones and UAVs—no separate display needed.
• APM/Pixhawk compatible telemetry input for seamless integration.
• Field-configurable via FTDI—customize OSD elements and layout.
• Compact and lightweight design for space-constrained builds.

Technical Specifications 🔧

• ATmega328P with Arduino bootloader
• MAX7456 monochrome on-screen display chip
• Compatible pinout for FTDI cable (programming/configuration)
