    Hi Oscar,
    Thanks for that great guide!
    My gopro worked for a while with external +5V (many power cycles) then it stops. I found that I can enabled it only when battery is connected. I disconnected Batt+ blue wire and it still working so I think that gopro may require connection with bms before start. I don’t know if anyone else has experienced that issue.

    Thanks for the help worked great! The only problem is that the Case we have from BetaFPV wont fit for the hero8. Is there a 3D printable version for the hero8 or do you guys know were to buy one? Thanks so much

    I was looking for a way to make the gopro have a remote button for turning it on and off with a wire. Is this possible at all? do you just cross the rec and the ground to make it record? Thanks in advance

    Thx for this it helped me a lot! I did the record button mod but as soon as i press it the gopro stops working! I have to unplug and plug it in again to function propperly. I connected it exactly like you did. When i plug in the original record button it does the same. Do you have an answer to that?

    Thanks for the informations; somthing is not clear for me :

    1. on the Hero 8 Pin-out, on the top of the photo, you show a ground and a power but on the previous photo, these 2 pins seems to be connected with a cable ?
    2. on which pins exactly should we power on the Hero8 ?

    Thanks Oscar for your useful informations.
