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

The notes are valid, I recognize the COM port is relatively easy to do in Windows, but if you do not have the FTDI board can not flashed the Mini OSD to load the firmware, therefore Hobbyking does not work and is not clear note that without this card does not work.
Hi, I would like to use this OSD with Mobius cam and Multiwii pro red board. While I am waiting for the parcel, I would like to ask you few things.
1. I want to flash rush-osd and I have USBASP programmer. Will it work? I have to solder 6 pins?
2. Do I have to use PAL mode for Mobius cam and boscam 500 mW FPV? I have to solder something again?
3. Can I power the OSD with a 5V BEC (Turnigy Plush 30A ESCs), taking from the pins on FC? Simply connecting to the OSD power pins or I have to bypass the voltage regulator in this case?
Buy the Mini Osd Hoobyking V1.1 and APM 2.5 EInstall the Mission Planer and I could not get it to recognize the Osd appears "failed to talk to the bootloader", all connections are fine. The specific question is: From the Mission Planer can do to recognize and operate the OSD directly as manufactured or necessarily have to Flashet Osd Mini with FTDI USB Controller Adapter - 5V for this to work. Hoobyking is not clear to notice that the Mini Osd must be purchased with adapatdor FTDI USB to make it operate.
I dont use APM but I use NAZE 32 boards. I cannot conect the 2 together to my computer or I get the same message as they share the same port so they must be set up seperately. Yes you need a FTDI to do this. I have found the smartfun one off fleabay works best
Hi RC Fun,
if you are using Windows you can just change the port of either one so they use different ones if you go to "control panel" click on "Device Manager" then on "Ports (Com & LPT" then just select the one you want to change then click on "Porte Settings" then on "Advanced" then you will see COM Port Number" click on that and pick the Port Number you want to use then just click on "OK" on both and that is that.
Hope this may help, Regards Poppy Ann.
Hi again, ok it is not unusual for me to get it all backwards, on the AMP board 2.5.2 i have it has a solder jumper to set it so it uses a different channel so it uses different urat (urat-0, urat-1 and urat-2) or that is what i believe it as (reading some of the instructions does not always help)
regards Poppy Ann.
Thanks guys, so the output voltage for the OSD has to be about 3.3V!? and therefore the HK Pilot current sensor need voltage regulation but the APM power module / current sensor delivers this voltage directly?
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.
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.
