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:
- Signal Orientation: Always insert with signal wires (S) facing upward to avoid reverse polarity.
- Parallel Control: Powers up to 5 servos/ESCs simultaneously (shared power bus).
- 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!
Thruster Safety: Quick Guide
1. For Your Safety:
- Keep Clear: Never put hands, feet, or anything near the propeller when it's plugged in. It can spin without warning and cause injury.
- No Water, No Power: Do not run the thruster in air for more than 10 seconds. It needs water to cool itself or it will break.
2. For The Thruster's Safety:
- Check Seals: Always check that the rubber O-rings are clean, greased, and undamaged before putting it in water.
- Avoid Debris: Keep it away from weeds, sand, and plastic bags. These can jam and break the propeller.
- No Regular Glue: Do not use normal threadlocker (screw glue) on any screws. It will crack the plastic body. Only use a kind that is safe for polycarbonate.
3. Simple Rules:
- Test First: Always test in a bucket or pool before going to open water.
- Rinse After Use: Always rinse with fresh water after use, especially in saltwater.
- Store Safely: Keep it in a case to protect it from bumps and dust.
Thruster Propeller Guide
1. Two Propeller Types:
- You get two propellers: one labeled "CW" (spins clockwise) and one labeled "CCW" (spins counterclockwise).
2. How Thrust Works:
- Forward Thrust (Recommended):A CW propeller pushes best when spinning clockwise.A CCW propeller pushes best when spinning counterclockwise.✅ Use this for maximum power and efficiency.
- Reverse Thrust:Both can also spin the opposite way to push backwards.⚠️ This works but is weaker and less efficient.
Quick Tip: Always check the label (CW/CCW) to make sure you have the right propeller installed for the direction you want to go. For the strongest push, use forward thrust.
What You Need to Run a Thruster？
The Thruster: The main unit, which contains a brushless DC motor.
- Power Source: A battery pack or power supply.
- A Controller: Something to tell it how fast and which way to spin (e.g., a remote control).
How to Connect It:
- If your thruster has a built-in ESC:
You can often connect it directly to a standard PWM receiver. - Important Note on Power:
If your receiver or ESC does not have a BEC (Built-in Eliminator Circuit) to power itself, you will need to add a separate BEC module. This provides the necessary power for the electronics.
Thruster making strange sound,broken?
It's normal for our thrusters to be loud.They use plastic bushings, so small movements between parts can cause sound. This noise is greatly reduced underwater, as water lubricates and cools the system.Never run them dry for more than a few seconds—it can permanently damage the bearings. Every thruster is tested to work properly.
