Thanks to user bangkomit for posting it (in the X4 quad thread).
That little device looks neat. It could also be useful to regulate voltage, both down and up, to power the camera from an external 4 cell NiMH pack.
But being a switching regulator, I wonder if it will have an RF noise issue with FPV video transmission? Might need to add a choke which would add some weight? Please post how this works for you.
