digilog.pk stocks a comprehensive range of USB cables, jumper wires, breadboard wires, banana plugs, audio jacks, header pins, terminal blocks, JST connectors, XT60 connectors, barrel jacks, and electronics cables for prototyping and production in Pakistan. Whether you need a pack of 40 female-to-female DuPont wires for your breadboard or an XT90 anti-spark connector for a high-current LiPo pack, we have it at competitive prices with nationwide delivery.

Why the Right Connector Matters

• Secure connections prevent failures — loose jumper wires cause intermittent bugs that are hard to diagnose
• Current rating matters — using undersized connectors on high-current circuits causes overheating and melting
• Correct pitch — 2.54mm, 2mm, and 1.25mm pitch connectors are not interchangeable
• Shielded cables for noise-sensitive signals — USB, audio, and SPI lines benefit from shielding

Cable & Connector Types

• Jumper wires — M-M, M-F, F-F; 10cm, 20cm, 30cm; 40-pin rainbow sets for breadboard prototyping
• USB cables — USB-A to Micro-B, USB-C, Mini-USB for programming and power
• Header pins — male single-row, double-row; 2.54mm pitch; for PCB and shield stacking
• Female pin headers — stackable; for Arduino shield connectors and PCB sockets
• JST connectors — PH 2.0mm, XH 2.54mm; for LiPo batteries and small electronics
• XT30 / XT60 / XT90 — high-current connectors for LiPo packs, e-bikes, and drones
• Barrel jacks — 5.5×2.1mm, 5.5×2.5mm; standard DC power connectors
• Terminal blocks — screw-type 2.54mm and 5.08mm for panel wiring and PCB power
• Banana plugs and test leads — for bench power supply and DMM connections
• Dupont crimp pins — for making custom wire harnesses with crimping tool

Common Applications

• Breadboard prototyping — 40-pin jumper wire sets for Arduino/ESP32 development
• PCB assembly — JST connectors for modular wiring in 3D printers and robots
• Battery pack wiring — XT60 and XT90 for e-bike and drone LiPo packs — see Battery & Charging
• Panel installations — terminal blocks for clean relay and sensor wiring
• Test & measurement — banana plug leads for bench power supply and oscilloscope probes

How to Choose

1. Current requirement — DuPont jumpers handle <1A; XT60 handles 60A continuous
2. Connector pitch — check the mating connector's pitch before ordering; 2.54mm is most common
3. Wire gauge — 24 AWG for signals; 20 AWG for moderate power; 18 AWG+ for high current
4. Locking mechanism — JST and XT connectors lock; bare DuPont does not — choose based on vibration environment
