Servo Splitter Y-Cable 300mm - 1 JR Male to 2 Futaba Female (High-Quality 22AWG Twisted)

Specifications:

• Cable Type: Y-Harness Splitter (1-to-2 Parallel)
  
• Length: 300mm (30cm)
  
• Connector A: 1x JR Male (Receiver Side)
  
• Connector B: 2x Futaba/JR Female (Servo Side)
  
• Conductor Material: Multi-strand Copper
  
• Insulation: Flexible PVC (Black/Red/White standard coding)

Key Applications & Projects

• RC Aeromodelling: Perfect for dual aileron or flap setups on a single channel.
  
• Robotic Arms: Synchronize dual-motor joints (e.g., shoulder lift) for double the lifting torque.
  
• Automotive: Control dual steering servos in large-scale RC rock crawlers.
  
• Animatronics: Mirror movements in eyes or limb structures efficiently.
  Redundancy Systems: Split signals for backup flight controllers.

The Project Evolution

• Prerequisite: You've likely built single-servo mechanisms like a simple pan-tilt bracket.
  
• The Upgrade: This Y-Cable unlocks Synchronized Actuation. By coupling two motors mechanically and electrically, you can double your torque output without upgrading to expensive industrial servos.
  
• Effort Level: Beginner. Plug-and-play simplicity.
  
• Hardware Needed: 1 Receiver/Microcontroller, 2 Servos, 1 Power Source.

Virtual Technician & Wiring Guide 

⚠️ Voltage Warning: This cable connects servos in Parallel. Both servos will receive the SAME voltage provided by the source. Ensure both connected servos are rated for your power supply (e.g., do not mix a 5V servo with a 7.4V servo on a high-voltage line).

Wiring Mapping:

• Black/Brown: Ground (-)
  
• Red: VCC (+)
  
• White/Orange: Signal (PWM)

Frequently Asked Questions (FAQ)

1. Does this split the voltage or the signal?
   It splits the signal and power in parallel. Both servos receive the exact same PWM signal and voltage.
2. Can I use this to reverse one servo's direction?
   No, this is a passive cable. Both servos will rotate in the same direction. You need a "Servo Reverser" module or a programmable servo to reverse one.
3. Will this work with digital servos?
   Yes, it is fully compatible with both analog and digital servos.
4. What is the wire gauge (AWG)?
   It uses standard servo gauge wire, typically 22-26 AWG, sufficient for standard high-torque applications.
5. Can I power two MG995 servos with this?
   Yes, but ensure your BEC (Battery Elimination Circuit) or power supply provides enough amps (approx 2-3A) for both motors.
6. Does it introduce signal lag?
   No, the copper connection is direct. There is zero latency added by the cable.
7. Is this compatible with Arduino/ESP32?
   Absolutely. You can plug the single end into a GPIO pin (via headers) to control two servos with one line of code.
8. Can I use it for ESCs (Electronic Speed Controllers)?
   Yes, for twin-engine planes or boats, you can calibrate and throttle two ESCs simultaneously.
9. Are the connectors gold-plated?
   Standard contacts are tin or nickel-plated, which is industry standard for these connectors.
10. What happens if one servo stalls?
    Since they share power, a stalled servo drawing high current might cause a voltage drop affecting the second servo.
11. Is the male connector shrouded?
    It is a standard JR male plug with a shroud, compatible with standard receiver blocks.
12. Can I daisy chain these to control 4 servos?
    Technically yes, but be very careful about current draw. Powering 4 servos from one receiver port is risky.
13. Do I need a separate driver for this?
    No, it connects directly to your existing receiver or microcontroller.
14. Will it fit into a breadboard?
    The male JR pin spacing is 0.1" (2.54mm), so it can fit into breadboard headers, though it is designed for pins.
15. Is the insulation heat resistant?
    It is standard PVC insulation, rated for typical electronics temps (up to 80°C), but keep away from soldering irons.
16. How much weight does it add to a plane?
    It weighs approximately 15 grams, negligible for most airframes.
17. Can I use this for LED lights?
    Yes, if the LEDs use standard 3-pin headers, you can power two strips from one port.
18. Does it have a ferrite ring?
    This specific model does not typically include a ferrite ring, as 300mm is generally safe from high-frequency noise.
19. Are the connections soldered or crimped?
    They are machine-crimped for maximum durability and resistance to vibration.
20. Is this waterproof?
    No, the connectors are exposed. For marine use, wrap connections in waterproof tape or heat shrink.
