The Servo Expander SE4 is a device that converts serial bus signal to standard PWM servo outputs. It offers up to four configurable servo outputs with optional period and fail-safe setting. The SE4 is a perfect choice for models with complex wing or tail mechanics where multiple servos may be connected to a primary receiver using just a single cable. In addition, if you are running out of receiver channels simply connect the SE4 to the receiver serial line and freely assign its own output channels.  

Supported protocols:

• Futaba: S.Bus/S.Bus2
• Graupner: SUMD, Hott telemetry for setting
• JETI: EX Bus
• Multiplex: SRXL 12ch, SRXL 16ch
