Owner: Jerry & Neel

We decided to continue using the off-the-shelf OSD because OSD chip MAX7456 has gone obsolete.

Requirements

• COTS features:

  • Arduino MCU

  • MAX7456 OSD chip

  • ISP header

  • PAL video format option

• minimosd

Research

• 2023 System Architecture

• Minim OSD Quick Installation Guide — Copter documentation

• current OSD: Holybro Holybro - Micro OSD V2

  • Camera: https://www.getfpv.com/caddx-baby-ratel-2-1200tvl-1-8mm-fpv-camera.html

  • Video Transmitter: http://www.mateksys.com/?portfolio=vtx-1g3se

• current OSD power specs: Power Distribution Architecture | Mandatory Airside Components

• MinimOSD (minimized OSD) is an on-screen display (OSD) system that utilizes an Arduino 328p processor along with a MAX7456 chip to handle the text overlay.
