Pin headers, JST, USB, terminal blocks, board-to-board and FFC/FPC are the main types. Pin count, pitch, current/voltage rating and mating-cycle life matter when choosing one. Board connections, power distribution, data interfaces and module mounting are the most common uses.

Frequently asked questions
What is connector pitch?+
Pitch is the center-to-center distance between two adjacent pins (e.g. 2.54 mm, 2.00 mm, 1.25 mm). The pitch must match for a cable and socket to fit.
How do I choose the right connector?+
Current/voltage carried, pin count, pitch, mounting type (through-hole/SMD) and how many times it will be mated (cycle life) are decisive. Use heavy-contact connectors for power and fine-pitch ones for signal.
What is a JST connector and where is it used?+
JST is a popular family of small, latching wire-to-board connectors (PH, XH, SH series). It is widely used for battery, sensor and module connections.
