What interface does the FC controller use
The USB interface allows connection between the FC and its configurator enabling the user to modify and change the the boards settings including the rates, PID's, receiver configuration, failsafe setup and flight modes. Onboard FC adapters and some FC expansion adapter cards can be individually configured as either initiators or targets ports. The FC Bus terminal block is a blue, removable, 4-pin terminal block that fits into a board-mounted pin header. When configured as a Fibre Channel over Ethernet (FCoE)-FC gateway, the QFX3500 switch supports the transport of native FC traffic between FC switches and the gateway's native FC interfaces. Only the QFX3500 switch has native FC ports and supports native FC connection to the SAN. It processes data from various sensors, runs complex algorithms, and makes hundreds of adjustments per second to keep your drone stable and responsive. The Flight Controller also connects to a radio receiver chip (RX) and accepts control input from the pilot who is flying the drone.
