Why Choose Both-Sided Pre-Crimped Cables?
- Both ends factory-crimped — Insert directly into KK 254 / KF2510 housings on both sides; no crimping tool or bare-wire soldering required
- PCB-to-PCB ready — Ideal for connecting two PCBs or modules that both use KK 254 / KF2510 headers, such as Arduino shields to sensor boards
- KK 254 / KF2510 compatible — Fits Molex KK 254 housings (2.54mm pitch) and all KF2510/KF254 equivalent connector housings
- 22AWG UL1007 wire — Flexible PVC insulation rated 300V/80°C; suitable for internal chassis wiring and PCB harness assembly
- 10 colors × 10 lengths — Color-code circuits and select exact lengths to minimize wire management overhead
Typical Applications
- Arduino shield-to-sensor board wiring harnesses
- RAMPS 1.4 / 1.6 board-to-board connections in 3D printers
- CNC machine controller-to-driver board wiring
- PCB-to-PCB internal chassis wiring in industrial control panels
- Raspberry Pi HAT-to-breakout board wiring
- LED driver board-to-power supply PCB connections
Compatible Housings
- Molex KK 254 series: 2695-02, 2695-03, 2695-04 ... 2695-12 (2–12 pin)
- KF2510 / KF254 equivalent housings (2.54mm pitch, 2–12 pin)
- Generic 2.54mm pitch female crimp housings (white, black)
Frequently Asked Questions
Q: What is the difference between single-head and both-sided cables?
Single-head cables have a terminal on one end and a bare stripped lead on the other — use these when one end needs to be soldered to a PCB pad or connected to a screw terminal. Both-sided cables have terminals on both ends — use these when both connection points use KK 254 / KF2510 housings.
Q: Is this a single wire or a multi-wire harness?
This is a single wire (1pc) with female KK 254 terminals on both ends. To build a multi-wire harness, order the required number of wires and insert the terminals into KF2510 housings of the appropriate pin count.

Frequently Asked Questions
Product & Compatibility
What is the difference between JST PH, XH, ZH, and SH connectors?
JST connectors differ primarily in pitch (pin spacing): SH = 1.0mm, ZH = 1.5mm, PH = 2.0mm, XH = 2.5mm. Smaller pitch connectors are used in compact electronics like drones and wearables, while larger pitch connectors suit general prototyping and power applications. Always verify pitch before ordering to ensure compatibility.
Are your connectors compatible with standard Arduino and Raspberry Pi projects?
Yes. Our DuPont 2.54mm connectors are the industry standard for Arduino, Raspberry Pi, and most development boards. JST PH 2.0mm is widely used for LiPo batteries in RC and robotics projects. We recommend checking your board's datasheet to confirm the exact connector type and pin count required.
What wire gauge (AWG) should I choose for my application?
Wire gauge depends on current load: 28–30 AWG suits signal lines up to 0.5A; 24–26 AWG handles 1–3A for moderate power; 22 AWG is suitable for up to 5A. For high-current applications, always use appropriately rated wire and connectors. Our product listings specify the AWG and rated current for each cable.
What is the difference between UL1007 and Silicone wire?
UL1007 is a PVC-insulated wire rated for 80°C and 300V, suitable for most indoor electronics applications. Silicone wire is rated for higher temperatures (up to 200°C), is more flexible, and performs better in harsh environments or high-vibration applications such as RC vehicles and industrial equipment.
Orders & Customization
Can I order custom cable lengths or connector configurations?
Yes. We offer custom wire harness solutions including custom lengths, connector types, pin counts, and wire colors. Please contact us via the Contact page with your specifications and we will provide a quote within 1–2 business days.
Do you offer bulk or wholesale pricing?
Yes. Volume discounts are available for orders of 50 units or more. Please reach out through our Contact page with your requirements for a customized wholesale quote.
How do I know which connector polarity or pin orientation to order?
Always refer to your device's datasheet or existing connector for pin 1 orientation. Our product images include wiring diagrams where applicable. If you are unsure, contact us with your device model and we will help identify the correct part.
Shipping & Returns
How long does shipping take?
Standard international shipping typically takes 7–15 business days depending on destination. Expedited options are available at checkout. Orders are processed within 3 business days. Tracking information is provided via email once your order has shipped.
