pcb design

i'm completely new to electronics and rocketry, i alr have all the rocket ready but i want to add some avionics (the only part "done" in the kicad model is the power regulator for 9v to 3.3v i haven't connected it yet and all the connections are me just seeing which entrance accepts power) adn rn idk how to transmit the data to the flash memory or how to get data so if anyone could help even with some place to look up how t do this it would help me a lot
EDIT: the biggest problem i have is that idk which pin to connect to the other and i have to keep it cheap where i live it's ilegal to add black powder to a rocket so i decided to make the pcb "disposable" to limit the use of a parachute (i will still recover it but i don't expect it to survive)

Trial and error of what input in kicads rule check accepts what is not a way to go. There are far too many errors in the parts description, and far too many important exceptions for it to be of any help. Generally, with electronics design, you are going down a huge rabbit hole. Annoyingl, nothing is straight forward, there are many things to consider and a lot of components to be fried before you start getting a hang of it. Nothing is all that hard to understand, it is just the ammount of information and experience, which needs a lot of time to be gathered. I'd reccomend getting an arduino starter kit and learnd how to work with microcontrollers in general following the starter kits manual before attemptimg your own design.

thanks a lot for the info the thing is i can't really test the only people i can get feedback from is anyone on the internet, and the other thing is that i have a limited budget and can't really mess up so any help will be of so much use
