Supports both manual mode and mode, switched by a button, with clear mode indicators for quick and reliable operation. Steering gear control with precision: 0.09 degrees accuracy, with a minimum change value of 1 us, enabling fine and repeatable adjustments. Direct debugging and testing option: you can directly use the 2second battery charging head to debug and the steering gear. Flexible control options in manual modes: knob adjustment control or serial port command control, giving you multiple ways to tune and test. Practical use scenarios: RC hobbyists and robotics prototyping: switch between manual and modes while dialing precise steering responses using a knob or serial commands. Calibration and testing in workshops: precision adjustments (0.09 degrees, 1 us steps) to achieve repeatable steering performance for components and assemblies. Field debugging and onsite tuning: power and test workflows enabled by the 2second battery charging head for convenient, onlocation validation of steering behavior. Key attributes at a glance: Function: dualmode operation with intuitive button switching and mode indicators Control precision: 0.09 degree accuracy, 1 us minimum step Power and debugging: supports direct use of the 2second battery charging head for debugging and Control methods: knob adjustment or serial port command control in manual modes Compatibility: supports both knobbased and serial command workflows for manual operation
