I initially assumed that an RX, for example, would be fed power through a single input (similar to a 4 plug extension lead) and that the power was then distributed to the 3 pin channels for any and all external devices to use. But as I';ve now seen video';s of RX';s being powering up via their Sbus input, then via the pins of channel 1, then the channel 3 pins, I guess it means that the RX can take power from any + pin that is fed the right voltage. May seem really simple to the initiated but I had no idea as nowhere seems to tell you this most basic of stuff!

They obviously take power from the LiPo via the ESC';s, so can you power a Tarot T-2D gimbal off the flight controller? Or is that not sensible even if it was possible? And if so, how do you power a gimbal and a Go Pro from the multi rotors LiPo battery?
Quote from: nate80 on Thursday,July 27, 2017, 18:22:28 The tarot t-2D gimbal requires DC 7.4V ~ 14.8V (recommended 12V, 3S LiPo) and has a working current: 200mA-500mA, so I could run it directly off a LiPo but I can also power it off a 12V 3A/5A UBEC?Can you power multiple things off a single UBEC safely? I';ve got the Tarot T-2D Gimbal (7.4~14.8V 0.5A), a Xiaomi Yi action cam (has a 1010mAh battery, so I';m guessing 5V 1A), and 6 x orientation LED';s (15.7V max and 2.2A). Could I run all that off a single 12V 5A UBEC? I don';t mind if the LED';s are slightly dimmer because they';re only powered at 12V.
Quote from: ched999uk on Thursday,July 27, 2017, 18:42:18 I believe the Xiaomi Yi will be destroyed at anything above 5v!!! So needs a 5v ubec.The Gimbal will be fine on 5A 12v ubec as will the LEDs. LED';s might be a bit dimmer as spec says MAX 15.7v. As for the control of the LEDs. That is an interesting one. I have 4 strips of LEDs, one per side, different colour each side (Front White, Right gReen, Left. Left bLue, and read Red). I can turn them on or off just by plugging them in on the ground. But I plan to fit a switch to the LEDs and my Gimbal. So that I can switch the LEDs on or off when on ground. Plus the gimbal takes 30 sec to initialise when lipo connected and as I use a SJ4000 I have to select video out each time it';s powered on. So have to wait to select video out before powering on gimbal.I also use a Naza and remote controlling LED';s does seem overly easy. Seems like easiest way it rx activated switch module. Something like this https://goo.gl/naFwu4 at about £5 for 20A switch.
