Digital Servo Tester – Multi-Function LCD Display (50Hz/125Hz/250Hz)

Product Details 

Key Features:

✅ 3 Frequency Modes – Supports 50Hz (analog), 125Hz/250Hz (digital servos).
✅ Pulse Width Control – Adjustable 800-2200µs for precise servo calibration.
✅ Multi-Device Testing – Sync signals for servos, ESCs, and motors.
✅ Compact & Lightweight – Only 75x38x15mm, 26.2g (portable for fieldwork).
✅ LCD Screen – Real-time pulse width/frequency monitoring.

Specifications:

Voltage: 4.8V–6.0V (No reverse protection! Wrong polarity = damage).

Signal Range: 800–2200µs (1µs precision).

Compatibility: Analog/digital servos, ESCs, brushless motors.

Use Cases:

✔ Test servo jitter/speed differences (e.g., robotics, RC cars).
✔ Simulate transmitter throttle inputs for ESCs.
✔ Calibrate micro-adjustments (e.g., drone gimbals).

How to Use:

Power On → Auto-enters manual mode (rotate knob to adjust pulse).

Press Select to cycle modes (Neutral/Auto/Manual).

Press Pulse Width to toggle 50Hz/125Hz/250Hz.

⚠ Warnings:

Never reverse polarity! (No refunds for burnt units).

Match frequency to servo type (50Hz for analog, 125Hz/250Hz for digital).

Multi-Channel Servo/ESC Signal Adapter (5-Port)

Connection Guide:

Pin Layout (Vertical 5-Pin Header):

Signal (S): Yellow/White wire (TOP position, facing upward)

Positive (+): Red wire (Middle)

Negative (-): Black/Brown wire (Bottom)

Key Notes:

1. Signal Orientation: Always insert with signal wires (S) facing upward to avoid reverse polarity.
2. Parallel Control: Powers up to 5 servos/ESCs simultaneously (shared power bus).
3. Voltage Warning: Ensure input voltage matches servo/ESC specs (typically 5V–6V).

⚠ Critical Safety Reminders:

• DO NOT reverse polarity (red/black wires). Damage may occur!
• Signal sequence matters: Misalignment can cause erratic behavior.

Application:

• Ideal for multi-servo robotics, RC model testing, or ESC calibration.

Why Buy This?

• Save Time – Diagnose faulty servos/ESCs instantly.
• Budget-Friendly – Cheaper than oscilloscopes for basic testing.
• Versatile – Works with RC planes, cars, robotics, and more!
