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

Hello. i just cant get my distance to home and arrow to work, arrow never moves and distance to home display never changes. all other info on the screen works good. i changed my parameters in mission planner to the settings posted here and it still wont work, any help would be great
Hy Hobby King Team , and Members ,
I got this MinimOSD connected to the APM2.6 , when I power up the whole I can see the boot screen , and the message "Waiting for HeartBeats" , then "Requesting Datastream" , and finaly the OSD display all the information given by the APM , BUT every 5/6 seconds , the display switch to "Waiting For Heartbeats" , then "Requesting Datastreams" and finaly the OSD display again the informations ...
Anyone have any Idea ? I can't find any informations about the baud rate the OSD talk with the other components :( 'cause somebody tell me that this is probably this parameter wich cause this issue :(
Thanks in advance :)
You have to set your APM right
I use minimosd-extra 2.4
There are a few requirements that have to be met, in order to be able to use MinimOSD-Extra.
1./ You need to use a Mavlink 1.0 compatible firmware on APM.
2./ You also need to have the data stream rates configured correctly. To do so, connect to Mission Planner. Go to configuration. Locate EEPROM parameters and verify that you have the following parameters configured as here*
SERIAL1_BAUD, 57 (telemetry output at 57600)
SR1_EXT_STAT, 2 ( 2hz for waypoints, GPS raw, fence data, current waypoint, etc)
SR1_EXTRA1, 5 ( 5hz for attitude and simulation state)
SR1_EXTRA2, 2 ( 2hz for VFR_Hud data )
SR1_EXTRA3, 3 ( 3hz for AHRS, Hardware Status, Wind )
SR1_POSITION, 2 ( 2hz for location data )
SR1_RAW_SENS, 2 ( 2hz for raw imu sensor data )
SR1_RC_CHAN, 5 ( 5hz for radio input or radio output data )
If you fly copter than you also need to set SR0 also:
Change accordingly and save the parameters to APM.
If you follow this steps, MinimOSD-Extra should work fine!
Ok Avi_Levy , I'll try this when I recieve a good FTDI Cable , because I thought I had a realy good one , but none worked , so for now , I cannot Do EEPROM Mapping and Character set update into the OSD , when this will done I think the OSD will works better :) I can tranfert the .hex files to the OSD , but as I haven't go any working serial cables I cannot setup the OSD :( I thought that my shields or ftdi cables were Ok , but no :( I had modify them for some other application so they work with them but in another way and not for use with OSD :(
For now I test the APM2.6 , great but strangely the APM2.6 seems to already have a compass embed ... and I have the NEO6 with compass too ... should this not make a double usage ?
I have the APM2.6 out of the case , and when I connect it to the computer with mission planner , without GPS , I can see the compass moving on the screen should this indicate that the board have compass ? I can read on the back of the board the 3DR logo so I think it is a real one ... If you know the APM can you send me some links I can read more about it ? ( yam1000r1*yahoo.fr ) Thanks a lot :)
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.
