Servo Tester and Speed Controler Power

This servo tester provides a simple way to test and control servos without programming or a microcontroller. It can also function as a signal generator for electronic speed controllers (ESCs). Connect up to three servos simultaneously and use the three operating modes to test range, speed, and neutral position.

Operating Modes

• Manual Mode – Turn the knob to control servo position and speed
• Neutral Mode – Returns the servo to its centre position
• Automatic Mode – Sweeps the servo back and forth through its full range

Key Features

• No Programming Required – Test servos directly without a microcontroller
• 3 Servo Connections – Test multiple servos simultaneously
• ESC Compatible – Works as a signal generator for speed controllers
• Compact Design – Lightweight and portable for bench testing

Specifications

• Voltage: DC 4.8–6V
• Servo Outputs: 3
• Dimensions: 46 × 32 × 16mm
• Weight: 9g

Ideal For

• Testing new servos
• Finding servo neutral position
• Verifying servo range of motion
• ESC calibration and testing
