Key Applications & Projects

• Giant Scale UAVs: Connecting tail-mounted rudder and elevator servos to a nose-mounted flight controller.
  
• Industrial Gantry Systems: Routing signals along linear rails for remote pick-and-place actuators.
  
• Animatronics: Managing cable looms in full-sized humanoid figures or theme park displays.
  
• Smart Home Infrastructure: Extending servo-controlled vents or locks across wall partitions.

Project Evolution 

• Past Projects (Prerequisites): If you have worked with 50cm leads, you likely encountered situations where your microcontroller was forced to sit too close to the mechanical action.
  
• Feature Upgrade: This 100cm extension unlocks "Distributed Actuation." It allows for a completely centralized control hub, simplifying maintenance and protecting your logic boards from the vibrations or environments where the servos are mounted.
  
• Effort/Requirements: Intermediate Level. Due to the 1m length, we strongly recommend using a Probots™ Logic-Safe  signal booster or a dedicated BEC (Battery Eliminator Circuit) at the servo end for high-load applications to ensure 100% stability.

Virtual Technician & Wiring

Safety Warning: 1-meter cables can act as long-wire antennas. To prevent EMI (Electromagnetic Interference), do not run this cable parallel to high-voltage AC lines or brushless motor wires without shielding.

Wiring Guide:

• Black/Brown Wire: Common Ground (GND)
• Red Wire: Positive Power (4.8V - 7.4V)
• White/Orange Wire: PWM Signal Input

Frequently Asked Questions (FAQ)

1. Will a 1-meter cable cause signal loss?
   It won't cause "loss" of the signal, but it can lead to signal "rounding" or noise. We recommend high-quality copper like this cable to maintain a sharp PWM square wave.
2. Is this compatible with 1/4 scale servos?
   Yes, it uses the standard connector found on high-power large-scale servos.
3. Can I use this for my 3D printer's BLTouch?
   Yes, it is the ideal length for large-format 3D printers like the Ender 5 Plus or custom builds.
4. Is the wire twisted?
   This is a flat ribbon cable, allowing it to be tucked neatly into narrow extrusion slots.
5. How much current can it carry safely at 1 meter?
   We recommend a maximum of 1.5A to 2A to avoid excessive voltage drop.
6. Can I use this for analog sensors?
   Yes, it is a shielded-style high-quality lead suitable for 3-pin sensors.
7. Does the 100cm length include the connectors?
   Yes, it is measured from tip to tip.
8. What happens if my servo jitters at this length?
   This is usually due to noise or voltage drop. Add a capacitor at the servo end or use a twisted-pair cable for extremely noisy environments.
9. Is it compatible with Spektrum receivers?
   Yes, the universal JR connector fits all major brands.
10. Is the signal wire White?
    Yes, following the standard Futaba color scheme.
11. Can I use this with an ESP32?
    Yes, the 2.54mm connector fits standard ESP32 development board pins.
12. Is the insulation thick?
    It uses standard PVC insulation designed for flexibility and heat resistance.
13. Will it work with 3.3V logic signals?
    Yes, the cable is passive and supports both 3.3V and 5V logic.
14. How do I stop the connection from pulling apart inside a wing?
    Always use a servo connector clip or heat-shrink over the male/female joint for 1m runs.
15. What is the weight?
    Approximately 25 grams.
16. Is it 22AWG or 26AWG?
    This version uses 26AWG high-strand copper for the best balance of flexibility and conductivity.
17. Is the center wire positive?
    Yes, Red (VCC) is always in the center for safety.
18. Why is this more expensive than the 50cm version?
    The increased length requires more high-purity copper and specialized testing to ensure 1m signal integrity.
19. Can I chain this with another 50cm cable?
    You can, but we advise using a signal amplifier for any run exceeding 1.2 meters.
20. Is bulk pricing available?
    Yes, please reach out to our team for bulk/educational discounts.
