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
