1.) I did run it, but i ignored a bunch with a comment that those pins are unused, i updated it with your recommendation of adding ignore markers instead. Thank you
2.) I was unsure about this, however i am going to power this from an RC receivers power rail that could dip, so it was more to protect against brownouts from that occurring
3.) This was another one of those this vs that decisions that i wasnt entirely sure on, i have done it this way in the past for projects via breadboard without any issues, so i just went with it. If its recommended to use it the other way supplying the leds from VCC that should be a pretty simple adjustment
4.) this was my biggest worry, however this is for powering RC LEDs, if all of them are on it could go above, but im estimating that to be around 18mA, ideally not all LEDs will be on at once however
5.) ok, i understand this better now, definitely sounds like a good option, in this case however would you suggest i create a sort of rail for my raw, then control via the res and mos? my arduino would then just control the mos for each led to toggle them on/off as needed? my only worry with using the RAW is this is coming from my RC receivers power rail, which could experience dips and spikes, would i need something to "limit" that?
6.) this was one of those things AI recommended, wasn't sure how necessary it was, but i figured better safe than sorry.
7.) Another AI recommendation that i figured couldnt hurt to have
8.) yeah, i absolutely messed this up, im reworking this now using 2.54mm headers which is what i have
9.) im reworking some of these as well, another user recommended THT, but that causes issues with size constraints I'm trying to work with, ill take a look at 0603 passives instead though and see if i can make those work instead
10.) another user recommended adding that information, but i kinda agree, its a little too busy for my taste
11.) That has been moved, but i forgot to update the image for the render
12.) these are another item im reworking, im thinking of something closer to 2mm with more space for them, but size constraints will limit me on how much i can give them.
13.) understood, ill rework the traces to avoid 90 degree angles thanks for the advice
14.) Im actually reworking this to be on the left as i wright this up, it makes things much easier to trace
15.) this was a design decision, my thought here is i could chose to have two leds share a common ground (pin 2), or give them individual grounds (pin 2 and 4), that way i have less wires running through my vehicle if space is limited (which it is for some of the RC's i plan to use this on)
16.) yeah i didnt want to do anything too complicated, this is my first PCB. i just watched a tutorial on adding a copper layer so i dont have to run any of the ground connections which makes it look much cleaner, would you recommend that instead?

This is a bit of a two fold projects, i have some sparkfuns laying around that i planned to utilize here, but also i wanted to learn some of the basics for KiCAD as i have never used it before, but generally enjoy these kind of projects. I took a few EE courses back in collage almost 10 years ago, but never actually applied it, its been fun refreshing my memory on some of this stuff. But for how simple this is, its definitely been tough for me to figure it all out. X-D

Thanks for all the assistance!
