Description

Mini OSD for Pixhawk Flight Controller

The Mini OSD for Pixhawk Flight Controller is a compact and lightweight On-Screen Display (OSD) telemetry module designed for FPV drones, quadcopters, multirotors, and UAV projects. Featuring an ATmega328P microcontroller with Arduino bootloader and MAX7456 monochrome video overlay chip, this module displays important flight information directly on an analog FPV video feed.

The Mini OSD receives MAVLink telemetry data from compatible APM2.5, APM2.6, APM2.8, Pixhawk, and PX4 flight controller systems and overlays flight parameters onto the camera video signal. Featuring PAL/NTSC support, an FTDI-compatible programming interface, a 6-pin ISP header, and two independent power sections, it is suitable for FPV monitoring, drone telemetry visualization, and DIY UAV development projects.

Features

  • ATmega328P microcontroller with Arduino bootloader
  • MAX7456 monochrome video overlay chip
  • Supports compatible MAVLink telemetry streams
  • Designed for APM and Pixhawk flight controllers
  • Displays telemetry on analog FPV video
  • FTDI-compatible programming pinout
  • Standard 6-pin AVR ISP header
  • Two independent power sections with LED indicators
  • Solder jumpers for combining power sections
  • Onboard 5V/500mA regulator for specified analog supply
  • PAL video selection solder jumper
  • Exposed HSYNC and LOS test points

Working Principle

The Mini OSD Module operates by receiving MAVLink telemetry information from a compatible flight controller through a serial communication connection.

The onboard ATmega328P microcontroller processes the incoming telemetry data, while the MAX7456 video overlay IC generates text and symbols over the analog camera video signal. The combined video output can be sent to an FPV transmitter or compatible monitor.

Depending on the installed firmware and available telemetry information, the module can display battery voltage, altitude, flight mode, GPS details, aircraft speed, and heading directly on the FPV screen.
