Question about GoPro Per 3.5mm microphone adapter

this adapter also works together with the RØDE Smart Lav+ Lavalier Microphone Black

Yes, the GoPro 7 will also have a USB-C port. The batteries will also remain the same.

I use the microphone adapter on the GoPro Hero 6, where it works without any problems. If the Hero 7 has the same connection as the previous model, it should work.
