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

bin trying to set this up managed to get all info up, except RSSI AND BATT voltage, but i get gray screen and osd or picture but not both, lol, any idea whats the problem brothers? also i should mention im using fat-sharks.
how are you powering the minimOSD... Do you use 2 batteries one that powered the 5V side and another for the video side? if you use one battery did you solder the jumpers or did you split the battery and power 5v and 12v with the same battery?
Guys, need an advice! If I buy this unit am I OK for FPV flighr with
1. SkyZone RC805 - 5.8Ghz 8 Channel AV Receiver
2. Boscam TR1 FPV All-In-One Camera and 5.8 GHz Transmitter with HD Video recorder
3. FY-20A flight stabilization unit
and if they are compatible? Lots of forums read, have a general notion of theme . That's all.
just to make sure, to use the RSSI on screen function, do you have to use a receiver with a data/RSSI pin? i own a orange 6channel 2.4ghz full range receiver, so i assume i cannot use the RSSI function?
thank you, so if i should change my tx/rx to a receiver that DOES have a data/rssi pin, i will still have to solder a small wire directly onto the leg of the atmega chip going to said pin in order to use the rssi function?
IF your board supports it, you should be able to use the RSSI values coming from your MultiWii board, or a MW pin (so you don't have to solder a small wire). Otherwise yes, you have to solder a small wire. I bought the version from "Ready tofly quads .c om" (remove spaces). That version is exactly the same except there is a second line of pin slots on the side that have direct pin inputs for RSSI and other functions.
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?
No, my PAL points are disconnected, but I'm using NTSC, but still I believe, you can use pal and not solder these points. Also, I'm powering it both ways - 5v from my APM, and 12v from my AV trasmitter power source .
I have just 1 issue left, from time to time, when I'm about to launch, the osd needs a restart, from the button reset, and after that it boots up normally. Sometimes it's on from the beginning. But that's it.
Are you powering your camera and minim OSD using the same battery? This may blow the minimOSD video chip...you should power the camera and transmitter with one lipo and the apm minim osd and esc with another lipo.... if that does not work try checking to see if you have pal or ntsc setup correctly for the camera in your minimOSD gui..
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.
