Function: Multi-purpose tester for checking and controlling servo motors, brushless motor ESCs, and PWM signals.

Operating Modes:

1. Manual Mode – Adjust servo/ESC position or throttle via knob.

2. Neutral Mode – Automatically centers the servo to 1.5 ms pulse.

3. Automatic Mode – Generates a continuous sweep (0°–180°) for servo/ESC testing.

Operating Voltage: 4.8V to 6.0V DC (via BEC, ESC, or external power supply).

Output Signal: Standard PWM pulses (1 ms to 2 ms, 50 Hz).

Channels: Supports up to 3 channels simultaneously – test 1–3 servos or ESCs at once.

Compatibility: Works with analog and digital servos, brushed/brusheless ESCs, and PWM-based devices.

Construction: Compact PCB module with potentiometer knob and 3-pin servo headers.

Current Handling: Can drive multiple servos (limited by external power supply capacity).

Applications: Ideal for RC model testing, robotics development, servo calibration, ESC setup, and hobby electronics.
