The Servo Expander SE4 is a device that converts the serial bus signal into standard PWM servo outputs. It offers up to four configurable servo outputs with optional output period and a fail safe setting.
The Servo Expander SE4 is ideal for reducing the wiring harness in the model to enable additional functions in addition to the flybarless system.
The SE4 is the perfect choice for models with complex wing or tail mechanics, as well as models with limited receiver outputs where multiple analog/digital servos can be connected to a primary receiver with a single cable.
If you need more receiver channels, simply connect the SE4 to the receiver serial line and freely assign the output channels.
