Servo Tester and Digital Brushless Multi RC ESC Speed Position Controller 3CH

Quick Introduction: Stop guessing where "centre" is before installing your servo horns! The CCPM Servo Tester is a mandatory tool for any RC hobbyist or robotics builder. Instead of setting up your entire radio transmitter and receiver just to centre a servo, this pocket-sized device generates precise PWM signals to test the range of motion, detect jitter, and set the perfect neutral point in seconds. It also doubles as a Digital ESC Checker, allowing you to spin up brushless motors and calibrate throttle ranges safely on the bench.

Detailed Specifications

• Input Voltage: DC 4.8V – 6.0V (Strict Limit)

• Output Channels: 3 Synchronised Ports (Test 3 servos at once)

• Output Signal: 1.5ms ± 0.5ms (Standard PWM)

• Output Current: 15mA (5.0V)

• Operational Modes: 1. Manual: Turn the knob to sweep the full range. 2. Neutral: Locks to precise centre (1500µs). 3. Auto: Continuously sweeps back and forth ("Window Wiper" mode).

• Dimensions: 48mm x 42mm x 17mm

• Weight: 8g

Quality Advantage & Differentiation: Why add this to your flight box?

1. 3-Channel Synchronisation: Unlike basic testers, this unit drives 3 servos simultaneously, making it perfect for swashplate levelling on helicopters or testing dual-aileron setups on planes to ensure they move in perfect unison.

2. ESC Calibration Mode: It acts as a manual throttle controller. Connect your ESC to the output, and use the knob to simulate 0-100% throttle—ideal for testing motor direction without risking a prop strike from a live radio system.

3. Vibration Testing: The "Auto" window wiper mode stresses the servo gears continuously, helping you identify stripped gears or overheating issues before you launch your expensive model.

Key Applications & Usage

• Servo Centring: Set the device to "Neutral" (centre LED) to install servo horns at exactly 90 degrees during assembly.

• Robotics Tuning: Verify the full range of motion for robotic arms and grippers without writing a single line of Arduino code.

• Thrust Testing: Use it as a manual throttle knob for bench-testing brushless motors and propellers.

What's Included & Required

• Included: 1x 3-Channel Servo/ESC Tester.

• Required: External Power Source (4.8V-6V Battery Pack or BEC). Note: If testing an ESC with a built-in BEC, no external battery is needed.

• ⚠️ CRITICAL SAFETY WARNING:

  • Input Voltage: The input limit is 6.0V MAX. DO NOT plug a 2S LiPo (7.4V) or 9V battery directly into the "IN" port. Doing so will instantly burn out the internal logic chip and potentially damage connected servos. Use a 4xAA pack or a 5V BEC.

  • ESC Connection: When testing an ESC, plug the ESC into the OUT side (not IN). The ESC's internal BEC will back-power the tester. Do not connect a separate battery to the "IN" port while an ESC is connected, or you risk voltage conflict.

• Pinout Reference (MANDATORY):

  • Left Side (Input - Power):

    • Top Pin (S): Signal (Not used for power input)

    • Middle Pin (+): Positive (4.8V - 6V)

    • Bottom Pin (-): Negative (Ground)

  • Right Side (Output - Servos/ESC):

    • Top Pin (S): Signal Output (White/Orange Wire)

    • Middle Pin (+): Positive Output (Red Wire)

    • Bottom Pin (-): Ground Output (Black/Brown Wire)

• Troubleshooting: Servos jittering? This often happens if the input power is too low (weak batteries) or if you are using a "Digital" servo on a tester designed for Analogue frame rates. Try fresh batteries first.
