Servo Motor Tester – PCB Design

A PCB design for a servo motor tester circuit, created using KiCad.

Overview

This project contains the schematic and PCB layout of a servo motor tester, used to test whether a servo motor is functioning correctly by generating a variable PWM signal to sweep it through its range of motion.

The project was developed to practice PCB designing.

Tools Used

• KiCad
• Snapmagic : for downloading footprint & 3D model of potentiometer

Reference

This project was created while following this YouTube tutorial by Ampnics, for learning and reference:
