Overview:
The FrSky RB-25S builds on the success of the previous trusted Redundancy Bus Series by adding new advanced features combined with a compact new design which meets the needs of users who want a flight-safe system built in a smaller size unit.
Triple Receiver Redundancy & Dual Power Input
RB-25S has been designed to offer both dual-power and triple-receiver redundancy. This provides the user triple receiver signal and telemetry redundancy by adding multiplex ports (RX1-3 IN / S.Port). Dual-power provides a safe and efficient way to power the system with your power sources connected via a pair of standard XT30 connections. The dual-power consumption system is designed to operate in balance mode, where it consumes the power line from either power sources depending on which has the higher voltage.
Advanced Stabilizer
The RB-25S offers an ADV Stabilizer function which is an upgrade over the original classical gyroscope stabilization modes. The ADV Stabilizer offers an advanced mode that provides more programmable stabilized channels and flexibility.
The classical stabilization mode has been enhanced with 5 additional stabilization channels, providing pin mapping to each channel in the multiple flight modes like Stabilization, Auto-Level, Hover, and Knife-Edge with an airplane model.
In the advanced stabilization mode, all the RB25S output pins are configurable for stabilization and additional advanced features such as File Sharing, Programmable Parameters, and Developer Access, etc.
Diversified Sensor Telemetry
The RB-25S also works as an extensive sensor module with various built-in sensors including diversified telemetry. The RB-25S also includes the high-precision telemetry sensor for monitoring altitude, vertical speed, etc. can be also used as an alternative to using a GR or S series receiver.
Power Switch Function
The built-in power switch function draws the support of using multiple types of external switches (e.g. NFC switch, Pin Plug, etc.) that enables flexible options on how the power can be switched on/off without the need to plug/unplug the battery connections.
