Yes, the media mod (Hero 9, Hero 10, Hero 11, Hero 12, Hero 13 Black) is compatible with your GoPro HERO9 Black. For best results, ensure your camera is running firmware version 1.22 or later.
The GoPro Media Mod for the Hero cameras offers a 3.5mm jack connection for connecting an external microphone, not a Type-C connection. To connect an external microphone such as the Rode Wireless Me, you therefore need an adapter that converts the signal from the microphone to the 3.5mm jack connection.
Hello, insofar as you have to remove the door that hides the battery and memory card in order to place the gopro in the media mod, the waterproofness of the gopro is no longer guaranteed. What's more, the media mod is not rainproof.
I would clearly say no here because the connections and the microphone are not waterproof and also the battery cover is open the Led can also be mounted on an underwater housing and there are also other housings.
Unfortunately, we currently have no information on when the item will be available and when we will be able to deliver it. As soon as something changes in this regard, we will post it here. Sorry.
