Gimbal Controller for Professional 3-Axis Stabilization

This advanced gimbal controller is designed for building high-quality 3-axis camera stabilization systems, ideal for both UAV-mounted and handheld gimbals.
It represents the next step in the evolution of professional stabilization technology, replacing the previous 8-bit SimpleBGC controller while maintaining full backward compatibility.

With improved processing power, smoother motion algorithms, and new functionality, this controller delivers enhanced performance, faster response, and greater stability — perfect for professional filmmakers, drone operators, and custom gimbal builders.

Key Features

Simplified gimbal tuning – minimal calibration required

Up to 5× longer runtime compared to non-encoder systems

Dual IMUs for higher stabilization precision

Instant torque increase for demanding motion angles
