Servo Motor Tester Module

A Servo Motor Tester is a compact and easy-to-use device designed to test and control RC servo motors and ESCs (Electronic Speed Controllers) without the need for a microcontroller. It generates a precise PWM (Pulse Width Modulation) signal, allowing you to rotate the servo smoothly and verify its performance. This tool is perfect for beginners, hobbyists, and professionals working with robotics, RC models, and automation projects.
