Description
This servo control module is a user-friendly, plug-and-play device designed for operating servo motors without complex programming. It offers three control modes, including manual knob-based adjustment and a centering function, making it well suited for servo motor testing, tuning, and educational applications. Built around an STM8S103 microcontroller, it generates precise PWM signals for accurate servo positioning.
Key Features
- Supports manual (knob-based) control for hands-on operation
- UART (serial) communication supported for external control from a host device
- Built-in auto-centering function returns servo to neutral position
- Can control two servo motors simultaneously
- High-precision control enables accurate angular positioning
- Utilizes STM8S103 microcontroller to output stable PWM signals
- Mode switching via onboard button
- Compatible with 2S rechargeable lithium batteries
