BLA1HH Series
Features
The BLA1HH Series is an actuator (servo module) designed for ailerons on medium-sized fixed-wing UAVs and for small robotic applications. The series supports dust and water protection compliant with IP64 standards.
A brushless motor is used to enhance durability, and support for Futaba's proprietary S.BUS system provides a high level of convenience.

- Control and Communication Standards
To support connection with Futaba RC receivers and various other controllers, the following communication standards are supported:- PWM: PWM signals used in conventional hobby RC servos
- S.BUS: Futaba’s proprietary serial communication protocol for hobby RC servos
- Position Feedback
The output voltage varies according to the angle of the output shaft, enabling continuous angle monitoring during operation.
