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

using with multiwii pro, fat shark teleporters 250mw set up, neo-7, got the video video but no osd, and if i remove the 12v power lead the picture goes very dark and bad quality, set up with gui all looks ok just no osd, any help from a fellow sky brother would be greatly appreciated.
Did you try hitting the reset button on the osd, after everything is connected and working, but without osd. Mine is like this, I almost gave up on it, when tried the reset, and it just said - osd - booting up, and started working ... :)
just tried this, the picture goes darker (like the 12v inst connected) then back to normal again, nothing else, are your PAL points soldered friend? also is your 5v coming from your receiver or your serial_1 5v?
If you are having problems with uploading firmware and character sets for min-extra...
Install the original firmware and character set (non min-extra stuff) from the download config-osd-20.zip - install the first ever made firmware and character set for it. After they are installed, you can then download the min-extra documents and load the new stuff.
I found that mine would not upload the character sets in the new extra firmware, but after installing the very very first firmware and character set, then uploading the new stuff - keeping in mind using the new minextra software uplaoder also All worked for me with no problems.
Also I did not have to power the 12v side to upload the character set successfully. It worked with out the 12v side being powered. Worst case connect a jst connector to your 12v lipo. I tried it both ways 12v side powered and not powered and it worked both times.
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.
