"Does the expansion port include the sd card reader?"에 답변The sd reader is it's own separate board inside.. Attached by a short flex cable. 3 screws, easily replaced!
"GoPro Hero4 Silver Not Recording Audio"에 답변I'm not at work however I believe the mic is in the top of the rear shell. When I get in tomorrow I will confirm this. There is the three flex cables that go to the board.. Check them, they can be tricky to keep in place during reassembly.
