The OSD standalone GPS is a handy little editing, among other things, for he that doeth FPV Fixed-wing.
The information displayed in your video will return the altitude, speed, distance, flight time, your battery voltage and contact information. These are very handy if you lose your machine (I also recommend saving your flights with a DVR to retrieve this information if your battery becomes disconnected during a possible crash). I use this site to recover the position.
It is also possible to receive the RSSI if your receiver allows. FrSky steering wheel, I prefer to have an auditory warning radio than multiplying the information in the video back.
To realize you need
I want to clarify that according to the chip of your FTDI, you can not put the original driver because you briquerez the dongle. A method exists for unbrick.
The firmware used is downloadable MWOSD here.
Start with soldering 5 pin header on the OSD (DTR, TX, RX, + 5V and ground), this is where you plug the FTDI and then GPS (Figure 1).
Connect the FTDI on the OSD according to scheme 2 and connected to your computer. (Be careful to cross TX and RX, so the TX of the OSD is on the FTDI RX and RX of the OSD is on TX).
A few Arduino ....
Go to the directory MWOSD the decompressed archive, MW_OSD and click the Setup file.
Your Arduino interface should open, go to tools, select type of card as "Arduino Pro or Pro Mini" and the port where your FTDI is connected.
Go in the "config.h" (1) and change the following values by removing the "//" if it is not already not:
#define MINIMOSD (2)
#define GPSOSD_UBLOX (3)
#define FIXEDWING (4)
#define BAUDRATE 115200 (5)
If another value is already without "//" be sure to add them.
Click the arrow (6) to upload the firmware in your OSD.
Unplug your FTDI
A little soldering ...
According to Scheme 3 below solder your 5V supply (after a beak, a stepdown, see your video transmitter if it has a 5V output). For the voltage of your lipo, come as solder the + and the mass of your LiPo. Connect ground and the signal from your camera and video transmitter.
Mistletoe MWOSD ...
Connect the battery and FTDI, throw the mistletoe found in the MW_OSD_GUI directory, and depending on your computer configuration, choose the directory (on my 64bit only the 32bit version runs), then start the MW_OSD_GUI application.
Connect the port (in my case COM4) (1) and set as the screenshot (Figure 4).
In Main Voltage, choose the number of elements of your LiPo (battery Cells) (2).
You can also show your nickname or name in Call Sign) (3).
You can move items by clicking "LAYOUT EDITOR" (4) and via the - or + select the item you want to move, then using the "UP, LEFT, RIGHT, DOUWN" have it where you want.
Click write (5) to save the changes.
Then you should upload fonts (font). To do this, click select, choose the desired font and click upload (6).
You can now connect your video reception and see the result.
The voltage of your battery is certainly not good, take a voltmeter to make the voltage of the LiPo and change the value in "voltage adjust" to obtain the correct voltage. At each change in value, you must confirm by clicking on write.
Connecting the GPS ...
It only remains to disconnect from the port, unplug your FTDI and plug your GPS as shown in Figure 5.
Take all for having a good GPS coverage and wait to receive the reception of different satellites. It can be long first.
good flights with your new option ...

- a micro minimosd
- a GPS (in my case a uBlox M8N)with which I withdraw the case or this one
- a FTDI
- the cable dupont
- optionally a spout / stepdown
