(This is part of a multi-part series on building a FPV mini 220mm quadcopter)

Since I’m building a FPV (first person view) based quadcopter, I need something that will display the copters telemetry to a video display or goggles.  I’m going with the Minim OSD v1.1.  I like that it is a mini Arduino (328P) based on-screen display board.

This board features two independent power and ground sections to isolate the OSD’s analog stage: a +5V section for the ATmega and the OSD’s digital stage, powered through the FTDI cable or other +5V source; and a regulated +5V section for the OSD’s analog stage, powered through the video in/out header and capable of handling up to +12V input.


• ATmega328P with Arduino bootloader
• MAX7456 monochrome on-screen display
• FTDI cable compatible pinout
• Standard 6-pin ISP header
• Two independent power sections with an LED indicator on each
• Solder jumpers for combining the power sections
• +5V 500mA regulator for up to +12V supply input (5-12v range)
• Solder jumper for PAL video option
• Exposed test points for HSYNC and LOS
