I haven’t used this website before so sorry in advanced if this is not how you ask a question. I was wondering if any f4 flight controller could work with ardupilot? I want to make my own custom board but I don’t know where to start.
Needs minimum 1MB, preferably (much preferably) 2MB of flash.
Search for „porting ardupilot to a new board“
Is there a page on the wiki that says everything you need?
Take a look at here.
