simple power distribution board
« on: October 18, 2015, 07:17:31 pm »
Hi everyone,

I'm into the RC FPV flying and I'm trying to simplify my portable ground station.

I would like to build a simple power distribution board to be able to use one battery to power up my gears.

I have some big 12v batteries and I need output of 12v/9v/7v/5v.

could this little design attached do the work, or will I burn in the fire or noobs :)

Thanks.

can you draw it so that it makes sense. Are the boxes supposed to be regulators ? I'm not sure you can put standard refu;lators in parallel.

How much power are you trying to convert and how many batteries are you trying to charge on one voltage ?

Sorry for my drawings.

I'm trying to supply my monitor, Googles, video splitter and video receiver mainly (plus other little things). I have some regulators, but their mA are little behind, so I thought if I put them in parallel I might get away with it.

I would like to reduce my ground station to a simple 12v LiPo Battery and do several step down to get all the voltages needed

I'm not going to charge any battery, just power up gear from one battery that will be main power supply

I would not put regulators in parallel, it can be done but needs extra circuitry.

Just get regulstors that can handle the power or you can boost one regulator with a transistor.

Or how about switchmode converters, that will save a lot of wasted power and give you more battery life if that is a problem. You may be able to get off the shelf modules.

thx,

I'll have to look up for switch mode converters, I'm not too acquainted with it.

I did it this way as I have many pieces sitting around and thought I could use them in this project.
