This is a mini Arduino based on-screen display board. It's tailored for use with ArduPilot Mega and the MAVlink protocol, and designed to be as small as possible.
It's main components are an ATmega328P 8 bit microcontroller with an Arduino bootloader, and a MAX7456 monochrome on-screen display. Programming is done through an FTDI-compatible 6-pin cable.
It 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
Specs: Voltage: 5-12v Dimensions: 50 x 18 x 10mm Weight 4g

No the problem was somewhere else. I connect 6 servos to apm2.5 board and amp board get only pver from (that unit what see how much power I use). And when I turn on transmit servos start use energy and voltage drop in apm I measure vas 16 volts. Thats why apm board restar and dont give heart beat to osd. Then I tahe of bridge from apm board and power servos from esc and problem solved. Now I dont now how instal flaps in apm :) I hope this information is helpful for someone and sorry for my English
excellent product, got it working with multiwii easier enough after flshing rush-osd and setting it up via rush gui. would be nice if you had jumpeers for your external monitor leads rather than having to solder onto the main chips legs but that it a problem with the initial design not hobbykings copy of that. i run mine off 5v with the soldered pads.
