Mini Servo Tester / ESC Tester

DESCRIPTION

The Mini Servo Tester / ESC Tester is a compact, standalone tool for testing servo motors and Electronic Speed Controllers (ESCs) without needing a microcontroller, RC transmitter, or computer. Simply power it up, connect your servo or ESC, and verify operation instantly — ideal for makers, robotics builders, and RC hobbyists in Singapore's growing maker community.

The tester generates RC-frequency PWM signals, making it useful for quick bench testing and precise servo control.

FEATURES

• Continuous adjustment of PWM output via the included knob cap
• Supports standard servo and ESC connectors (JR/Futaba-compatible 3-pin)
• Compact and portable — no external software or drivers required
• Low-cost solution for pre-deployment motor and ESC verification

APPLICATIONS

• Testing and calibrating servo motors for RC vehicles, boats, and aircraft
• ESC (Electronic Speed Controller) endpoint and calibration testing
• Robotics joint and actuator verification before final assembly
• Gimbal servo setup and alignment
• Drone and quadcopter motor-controller bench testing
• Educational use in electronics and robotics classes
