Pin-Port Mapping

Port	Left Pin (-)	Center Pin (+)	Right Pin (S)
PWM IN	Common Ground	5V Out	PWM Input (From Master RX Switch)
SBUS IN 1	Common Ground	5V Out	SBUS Input 1 (From Master RX Signal)
SBUS IN 2	Common Ground	5V Out	SBUS Input 2 (From Slave RX Signal)
SBUS OUT	Common Ground	5V Input	SBUS Output (To Flight Controller RX)

Physical

• Connectors: Standard 2.54mm pitch 3-pin headers (GND, 5V, Signal).

• Compatibility: Fits standard servo connectors (Dupont).

Electrical

• Operating Voltage: 5V DC (Supplied via the SBus OUT rail from the Flight Controller).

• Current Consumption: < 100mA (Excluding connected receivers).

• Signal Support: SBUS (Pass-through).

• Switching Logic: PWM (1000us - 2000us).

Protection & Safety

Failsafe Behavior: The system relies on the Master Receiver's failsafe settings. Ensure your Master Receiver is configured to output a Low PWM signal on the switch channel if the link is lost, forcing the system to default to the Master port.
