I just incorrectly answered a question recently because of some confusion about the size of the onboard dataflash of the APM 2.0. There is a lot of info out there stating it's 16MB! It's 4MB and that is a huge difference. I was wondering if a chip change could increase the memory from 4MB to 8-16MB because our Arduloon project needs at least 8MB to record a mission.
I don't think it is clear either that data flash cards do not work in the APM 2.0. There is no way to use them to increase the dataflash memory.
Any comments appreciated on how to possibly increase the size of the dataflash or if it's just not possible? Thanks for the help-
