The FrSky RB –20 is a switchboard module that can operate 2 receivers and 2 batteries to provide you with total peace of mind when flying your models. The RB-20 has a higher operating current and supports high-current servos, when previous redundancy products did not. One of the best upgrades on the RB-20 is that it can switch telemetry automatically between RX1 and RX2.
Like other redundancy products, you can run your servos from the switchboard with complete protection from high voltage overload. The RB-20 also supports Smart Port telemetry for your FrSky transmitters and will provide telemetry feedback for voltage and overload indication.
