I just recieved my simple OSD XL today and I'm impressed with its quality. I'm currently in the process of making sure I have all the connections right so Im bound to have a couple of questions pop up during the process and was wondering what are the batt output solder pads used for on the current sensor? I know the input is to power the OSD but the the purpose of the output solder pads confuse me slightly. Can I use it to power my video tx?

Does the OSD need powering from a lipo when connected to the computer or will the usb programmer handle the power through USB?
Current sensor is not designed (mainly) for powering OSD but to measure current from battery to the ESC/motor. So the output solder pads are for connecting power lines to ESC... But if you want to measure current/consumption of your A/V system instead of motor, you can use the connection as displayed on the picture - there is no use for output pads in this case.
When connecting to the computer, you must use external battery - in fact, first you should connect battery, OSD will power up and then you may connect computer cable. Doing it other way you may damage/erase firmware and settings in OSD!

I know the current sensor is to measure the current from the lipo but I also thought it served as the purpose for powering the OSD. Thanks for clearing things up. My FPV system is separete from my heli's main lipo mainly because in the forums it was recommended that I do that in order to avoid problems. The systems also fairly low voltage with the transmitter working on 7.4v and the camera working on 5v. Whats more important video signal or heli power hmmmm.
A picture speaks a thousands words so I took a pic below
My iftron transmitter takes raw audio input from my electret microphone and works fine but Im going to need to find a way to connect it to the OSD because the problem is that it doesnt have a one cable carrying the processed audio signal.
That doesn't look quite right. The Input is where you connect your lipo that you want to measure the current consumption of (usually flight pack). The output is where those leads then continue on to the esc. The current sensor works inline with the power leads, so you have to have something connected to the input and output of it.
I've modified your photo to show you how it should be hooked up if you want to measure the current consumption of your video system.

I could be wrong though as I never actually got round to using my current sensor.

I decided to read the current from my helis lipo so I have the input connecting to my helis lipo and the output connecting to my motors esc, that right? One word of concern, the lipo doesnt power the things like the video tx and camera right? because if 11.1v goes to my camera the electronics in it will burn out.
Edit:
Just saw youre edit, thanks, its same to what I just soldered, providing that the OSD doesnt power anything else other than whats connected to the output on the current sensor it should be ok as it would give me the option to either connect to my heli esc + lipo or lipo for fpv system.
I use a 3s lipo to power my OSD. I have that plugged into where you have the current sensor and then I use a servo Y lead to power my 12v video tx and then I put a 7805 regulator inline to power the camera. Makes a very simple setup. I could also still use the current sensor to monitor my flight pack current consumption or to power the whole setup.
Again, a pic speaks 1000 words. I can use just with a lipo as in the picture or I could plug the current sensor into the same place as where the lipo is now and have a 1 battery setup to power my entire aircraft/fpv system and monitor the current consumption at the same time.

What is batt .2 used for in the calibration settings and how do u actually save these settings to youre OSD?
http://www.flytron.com/fotolar/simpleosd..._beta1.jpg
I'd aprechiate it if someone goes through and explains these settings with me Im not 100% sure as to what each one does for example what the hell is Analog Sensor Design
I am fighting with Simple OSD as well. Just one question.
Is there any difference between variants recommended by Flytron - video transmitter (VTX) charging connected to OSD, or variant above when VTX charging is connected to the battery directly or through battery sensor?
Thank you for ideas in advance.

You can save this setting with "Write Cal. Values" button. We are using this calibration values for fine tunning voltage, current and rssi pins. If you wants auto calibration without fine tunning, i will release new firmware in 2-3 days, you can load it.
Analog Sensor Design is for designing your personal analog sensor input on AN1 pin. You can use ultrasonic distance sensor, altimeter, thermometer or any analog sensor with this option.

you can use both ways for supplying your VTX, 2 sides completely same.
Hi, I still quite dont understand what batt .2 is used for exactly.
At the moment the information on my display is all jumpy and the text is almost in italics. Ive seen peoples videos with the information separated with larger gaps but cant work out how its done.
Also is there as way to make the black background more visible I can bearly see it, surley having a drop down menu to set the text size of the OSD information and the transparency level of the background wouldent be too hard?
Along with the OSD XL edition I have a current sensor and GPS, what do I need so I can calculate the distance because at the moment it stays at 0.
