Guys, if you read Chief link on Black5 teardown, https://gethypoxic.com/blogs/technical/ ... ware-study
what was previously hero bus ( expansion port ) on rear of Hero4/3 is now turned into USB-C, any 3rd party device must first get GoPro approval since there is a chip which defines FRIEND of FOE for any special device connected via the USB_C , unless it is simple USB2.0 charging.https://gethypoxic.com/blogs/technical/ ... interfaces
This is also important as USB-C standard from USB.Org is implemented properly in a GoPro ( GP got to pay licence to USB.Org for sure ), so that the fast 3amps charging can be conducted.
When this Google guy first bought many USB-C cables and chargers from Amazon, he found out that many are so bad, it can burn out the device.https://www.reddit.com/r/Nexus6P/commen ... th_benson/http://www.androidcentral.com/what-look ... d-adapters
Even 0.5 amp USB 2.0 cables, many are craps, let alone 3 amps approved USB-C cable.
So before you plug any 3rd party device using USB-C to your USB-C camera or USB-C smartphone, do some proper check first. USB-C is much more complex than USB2.0/3.0.
