Cables & Connectors

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

How to Choose

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