Hey fellaz,
placing a order with JLBPCB and I'm trying to get together a bunch of different pcbs to order at once to save on shipping. I have a bunch ready to go but want to make one more...
I had previously asked a while back about a simple circuit to protect against short circuits and reverse polarity. I'm big into building DIY racing quadcopters. there's a large group of us in my area that all fly together. you can buy pre-made "shortsavers or smoke stoppers". some of them are a little more complex than others and some just use a resettable fuse. but I would like to make some of my own pcbs that I can hand out to everybody instead of spending $20 on a premade solution. I would like to just make it very simple and don't mind going the resettable fuse route.... but I've also seen some that use 2 resettable fuses... which I think is just there in order to light up a error indicating LED
below I have included a few pictures. A couple or of pre-made smoke Stoppers. and I've included my schematic of a simple one just using a resettable fuse and a schematic that I was given on my old Forum post when I asked about a short circuit protection which are using to npn or to PNP transistors or mosfets but they are not labeled.
again I think I'm just going to use the resettable fuse approach since that is what we use already but I would like to maybe Implement reverse polarity protection as well. but if the other two schematics offer a way better or safer solution I wouldn't mind going that route as well but again I don't know what transistor or mosfets to use
so somebody could take a look at my schematic just to verify that it will work which it should since I just copied it off a premade solution and how hard it might be to implement reverse polarity protection. and if I would be better off using a different method included in the other schematics.l
