There is a micro in there, maybe, I want to have a standalone pcb that I can add to the rest of the project(at least for now), so I can test it, and even if I end up with a micro in there it will be sleeping for hours, so it wont be able to nurse the MPPT, lipo charging IC's are cheap and TI as a lot of them, having a one chip solution would be neat, but its not the end of the world if I really need to use a couple IC's, but I would prefer to not end doing it with a micro, I dont trust my code lol.
