How to power FPV set up???

[neil-liverpool]

Im setting up Fpv with - boscam 5.8ghz rx and tx, sony nex 5r camera and a hdmi to analog converter, im not sure how to power the tx and the converter.

The tx needs 7-15v, I would of liked to power it straight from the battery but im using 4cell so it will be over the max 15v.

The HDMI convertor needs 5v, could this be powered from + - on the servo lead that comes from the escs?

Also the boscam has a power out cable, does anyone know what voltage it is??

the boscom VTX is 12 v

I run mine from balance plug off the battery but im 3s

you can get a 12v ubec from HK that will run off your 4s   http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idproduct=18788

but they sell out pretty fast

My boscom RX i run on a 9.9v life battery as 12v it gets very hot

Don';t power the video from an ESC BEC, as it will be quite dirty power. Get a separate 5V UBEC.

I believe the power-out on the boscam is just a pass-through. There';s a 0 ohm SMD resistor (there';s an oxymoron) in-line  that seems to act as an unintentional fuse. No idea what it';s there for, but you';ll find loads of people online who have popped it with varying degrees of damage to the board.

thanks for the replies.

I have ordered a ubec.

for now could I use one of my spare ecs to power it ?, it will only power the convertor.
