Yes, it does that.

Guys perhaps it's been asked before. Can we use these as an FPV camera? For example can I plug the USB Cable right a video transmitter? It would also probabbly need a wide angle lense. Here is some video with the camera velcro / zip tied on my quad.

I was not happy with using using the USB connector for AV-OUt so I had to fix the problem.

Result, added micro JST conector specifically for AV-OUT and 5V power.


(The white thing is double-side glue sticker, need to trimm it a bit)

Micro JST conector with 4 pins, it only has video and power as I didn't knew where to get audio. If someone knows I'd like to add it.

It was a long and painfull process to solder and fit it as the USB conector acts as a heatsink and dissipates all the power from the soldering iron.
I've connected the wires to it what will allow also to feed 5v of input like the normal AV-out USB cable. I already use other vTX kits that use the same micro plug so I can reuse them now with the #16 v2.


(added a dab of hot glue oever the wires to make sure they don't receive any stress and get loose)


I call it now #16 v3.


Btw when opening the camera i noticed several pads these four looked particularlly interesting as they two were marked as TX & RX, any idea what is this? Serial connection???

Probably... unless you are REALLY fast with making the connection change and there is a minimal capacitor in the circuit to keep the clock running during the swap!

Yes, FPV is discussed all over this thread in the last couple of months... ever since the V2 came out with video out. Either use the thread search link, or just browse back through for your areas of interest.

Are you sure your battery is fully charged? The green LED should be on while charging. Charging takes from 2 to 2.5 hours.

If the green LED doesn't come on, then you most likely have a defective USB cable or power supply. This is common problem. The first step is to ensure your battery is fully charged. Try a different USB cable, they are standard. If it still doesn't work, try yet another cable!

Once fully charged, you can do further testing by starting a recording and then connecting your camera to your computer or an external power supply. The recording should continue.

It doesn't matter if the card is in or out when you press the reset button. The reset button basically "shorts" the processor which forces the firmware to start running from scratch. It does not affect the real-time clock.



No disaster here! You can even install the very first firmware version that existed!
I made some tests and:
  1. You were right: I was trying to capture short footages but the battery was flat;
  2. I was right: I had the proof that long recordings were not running out of battery because the last scene of video was me grabbing the camera to switch it out.

By the way, I find the image quality of V58 better than the old firmware so I'm already satisfied just by this.

You are all doing a great work, from hardware to firmware to gui. Kudos.

You can easily use internal battery with jumper ON white/black wire. The external battery can be connected using servo cable connecting red/black wire. I use 3.7V Li-ion cell phone battery and it works well.

Nice job!

May I suggest that it would be even nicer to have a "miniusb to iso 3 pin" short cable. It could be a good power supply system from the airplane battery (or any airborne battery) to the camera with no additional wires come out from #16.

Maybe eletoponline should start to sell it along his other useful stuff.

The mini-USB cable that is for FPV use and that comes with the V2 cameras already does this. It has a +5V IN plug terminated in a standard three pin servo connector (but with only two wires in it for +5V and ground). It also has a similar servo plug with the video out signal and ground wires.

If not can you point me to the ones that will? If they will work how many will I need to work in the room and the room is about 12'x14' and there will be no lights on.

Tom please tell me if you want me to stop cause I know it is off topic.

This is not going to work to light a room enough to record anything useful. The camera can "see" many LED's when pointed at the LED, but these tiny LEDs cannot illuminate a room such that the camera could record the reflected light from a room scene. Well... maybe if you had thousands of them. This camera is not a good choice for indoor low light recording from any light source.

Some Google searches might locate a camera that does what you want, but this would be off topic for discussion here, as you guessed.

I refocussed my B lens by carefully scraping all glue from the threads, then unscrewing while firmly gripping the cmos housing. It's risky, you can tear the ribbon cable.

Most are short focussed, so a very mild negative diopter lens added might work. Salvage from a pair of specs.

You must be able to rotate the lens and screw it in/out (maybe 1/4 turn either way) to re-focus it. Did you try to chip away the glue in the threads with a needle. That can often allow the lens to be rotated a small amount... enough to adjust the focus. But be careful to hold the square CMOS plastic module VERY securely when attempting to turn the lens, and don't force it. You can crack the plastic or the traces in the ribbon cable.

Search this thread for other tips on freeing the lens. Some have suggested acetone to weaken the joint, but it's highly flammable and could wick into the lens between the elements and cause other problems.

Or, you can get another CMOS/lens module and plug it in.

the problem is there isn't any visible glue. I'm hoping this isnt the new way they are "fixing" their lens.

Negative lens

These might work, come as low as -1.5 diopter, seem no prescription needed for swim goggles
