Support Manual Mode and ToCenter Mode, switchable via function keys. Key features potentiometers, no programming required. 8channel potentiometers and servos are controlled in onetoone correspondence. 8channel servo controller, suitable for debugging and testing 5V8.4V servos. Supports manual adjustment, quick centering, and Passing Stream Protection. Onboard and stable 8bit MCU generates resolution PWM signals for accurate control. Steering gear control accuracy: 0.09 degrees (PWM minimum change value 1us). Benefits and why it matters Simplified setup: no programming needed to start testing and tuning 8 channels of potentiometers and servos. Precise control: resolution PWM with an 8bit MCU delivers accurate servo positioning, essential for finetuning steering and motion. Flexible operation: switch between Manual Mode and ToCenter Mode using function keys to suit testing, calibration, or demonstrations. Broad compatibility: designed for servos in the 5V to 8.4V range, making it suitable for a wide range of hobby and educational projects. Robust protection: includes Passing Stream Protection to help maintain stable operation during testing. 23 practical use scenarios RC hobbyist debugging: quickly pair potentiometers with corresponding servos to test multichannel control without software development, enabling rapid iteration on steering and routing mechanisms. Robotics prototyping and training: use manual adjustment and quick centering to calibrate steering gear and servo responses in earlystage robot builds or classroom projects. Precision demonstration and education: demonstrate resolution PWM control and 0.09degree steering accuracy in teaching labs, illustrating how small PWM changes translate to precise mechanical movement.
