BLA15 Series
Features

The BLA15 Series is an IP67-compliant servo module designed to meet a wide range of application needs.
While maintaining the long service life and environmental resistance performance of the BLA21 Series, the BLA15 Series achieves approximately one-third the size and weight of the BLA21 Series, providing a more compact and lightweight solution.
The series is available in models compatible with DroneCAN v1 (formerly UAVCAN v0), as well as models supporting PWM / S.BUS communication.

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
Please note that these communication methods cannot be used simultaneously.
