Hello everyone!
I'm new to the FPV world and purchased components following some tutorials on YT.
Mamba F405 mk2 stack came with a schematic that didn't quite understand:
How does those red and grey dots be intepreted and ...
...should I power my Tramp HV to 5V, 9V or VCC (as some video I've seen)?
See image below

Thank you for the help
