I am building a Tarot FY680 with Naza M V2 and Zenmuse gimbal for my Gopro. I need some help on how to setup t he separate power system for the accessories. I want to run the motors and flight controls off a 3S/4S 5000mah and then have a completely separate power system for the Zenmuse, Gopro, Video Tx and IOSD. The motor/flight control side is straight forward but the accessories system is what I need help on. I'm guessing a 3S 2000mah with a voltage regulator. But all the voltage regs that I saw on Hobby King only have at most 2 outputs, so do I then run the regulated supply to a board and then attach the other systems to this???
