Gimbal power supply

[Rustydiver]

I';ve just fitted a aeroxcraft gimbal to a set off their landing legs its for a 4s battery can I just wire it to my f550 circuit board where the battery connectors are soldered too.
Do i need to connect it to my naza.?

At the moment I have no spare channels on my tx just want to use it as a steadying device on the camera. In time one going to get another cheap tx so my son can control the camera and give him live view video.

Most of the Alexmos clone boards seem to operate at 3S level. I seem to remember reading they will power up at around 5V (from USB for instance) but to power motors require 9v-12v. If this is the case 4S is obviously a bit pokey.

The question then arises how is the board getting it';s voltage. I can lend you my experience which will hopefully save you the same fate as me. I loaded 12v into the power input and then connected the usual servo lead into the board from my Flight controller.  :embarrassed Magic smoke time. You';d have thought having the 3 pins there for your standard servo lead it would take the additional voltage from the Naza. Sufficed to say for the subsequent replacement I only connected the Signal pin and all was well
As I say, this is for the bog standard eBay cheapie controller, by no means scientific.

It was set up from aeroxcraft to run from a 4cell battery.

Just wired it up without connecting it to a tx and it works all fine.
It stays all level when moving the hex.

Yeah, most of these boards are fine at 4S, but anything beyond that and you need either a second battery or a step-down regulator that can handle the load.
