Hey, thanks for your feedback, I was pretty sure I updated the diagram to make things abit clearer but not sure what happened, so I will get this updated to make it as clear as possible.
And I see the problem with the closeup diagram, so I will update that, but for the buzzer, that is how you connect it as the software controls when it beeps, its just the closeup diagram (Naze32-Rev6-pinout3.jpg) which is wrong.
