Servo Extension Cable And RC Harness Builds
Compact signal and power harnesses for RC aircraft, robotics, camera gimbals, FPV payloads, and prototype electronics.
We build custom lengths, gauges, pinouts, and connector combinations across JST PH, XH, GH, ZH, SH, EH, VH, Molex PicoBlade, Harwin M20 DuPont-style connectors, and standard servo leads. Cross-connect flight controllers, receivers, payload boards, and actuators without hand-crimping every prototype cable.
Why MiniProto
Professional Harnesses Without The Wait
Small Connector Experience
JST, PicoBlade, Harwin M20, and servo-style leads need careful crimping, pin checks, and strain relief. We build them repeatedly.
Custom Lengths And Gauges
Specify short board-to-board jumpers, long servo extensions, branch harnesses, or mixed signal and power cable sets.
Drone And Robotics Ready
Pair these signal harnesses with our drone power and Pixhawk wiring solution pages for a complete UAV wiring package.
Technical Specifications
Compact Connector Options
Common RC, robotics, and electronics connector families used for servo extension cable projects.
| Connector | Pitch | Gauge | Typical Use |
|---|---|---|---|
| JST PH | 2.0 mm | 24 to 28 AWG | Battery taps and compact boards |
| JST XH | 2.5 mm | 22 to 28 AWG | Balance leads and board wiring |
| JST GH | 1.25 mm | 26 to 30 AWG | Flight controllers and sensors |
| JST SH/ZH | 1.0 to 1.5 mm | 28 to 32 AWG | Micro electronics and FPV |
| Molex PicoBlade | 1.25 mm | 26 to 30 AWG | Camera and payload boards |
| Harwin M20 | 2.54 mm | 22 to 28 AWG | DuPont-style development wiring |
| Servo Leads | 0.1 inch | 22 to 26 AWG | RC receivers, servos, gimbals |
We verify pin orientation because small connector families often flip wire order between mating halves.

Process
From Requirements To Tested Harnesses
Choose Connectors
Send connector families, pin count, wire colors, gauge, and orientation notes.
Confirm Pinout
We check mating direction, reversed pin order risk, length, branch points, and labels.
Build Small Leads
Cables are crimped, inspected, continuity checked, and packed by harness type.
