RS485 does not support arbitrary topology, because arbitrary topology will produce a large number of standing waves and reflections at the branch. This is due to impedance discontinuity.Impedance discontinuity:At the end of the transmission line, the signal suddenly encounters little or no cable imp
With the continuous development of UAV technology, this kind of micro-aircraft has penetrated into every field of our life, and the steering gear, as an important aviation component, is increasingly widely used in UAV. This paper will discuss the key role of steering gear in the safe flight of UAV,
