Pin Header & Female Header connectors are commonly used board-to-board connectors in electronic products. They are widely applied for connections between circuit boards, as well as between modules and mainboards. Based on different structures, pitches, row configurations, and mounting methods, these connectors can be categorized in many ways. The following is a summary of the common types:

1. By Pitch

1. 2.54mm (Most common, widely used in development boards and modules)

2. 2.00mm

3. 1.27mm

4. 1.00mm

5. 0.8mm / 0.5mm (High-density applications, commonly seen in smartphones and precision devices)

2. By Number of Rows

1. Single Row

2. Double Row

3. Triple Row

3. By Pin Length and Form

1.Straight Pin

2.Right Angle Pin

3.Surface Mount (SMT)

4.Through-Hole

4. By Terminal Type / Mounting Method

1.Board to Board

2.Wire to Board

3.Board to Wire

4.Pluggable (Detachable)

5.Non-Pluggable (Permanent)

5. By Connection Direction

1.Vertical

2.Horizontal / Right Angle

6. With or Without Housing (Positioning Frame)

1.Box Header

· Provides fool-proof design and easier mating

2.Without Housing (Standard Pin Header)

7. By Female Header Structure (Female Header Specific)

1.Round Hole

2.Square Hole

3.Double/Single Plastic Insulator

4.Stacking Female Header

8. With or Without Positioning Pegs

1.With Positioning Pegs (For accurate alignment and enhanced fixing)

2.Without Positioning Pegs

Common Application Fields

· Microcontroller development boards

· Industrial control mainboards

· Communication devices

· Drone/RC modules

· Display connections

· Modular design products (e.g., Arduino, Raspberry Pi)

If you are a manufacturer or purchaser, the following specifications are typically required when selecting a connector:

· Number of pins

· Pitch

· Number of rows

· Insertion direction (Straight or Right Angle)

· Mounting type (SMT or Through-Hole)

· With or without positioning pegs / Plastic height

Whether used in development boards, power modules, or complex multilayer mainboards, pin headers and female headers provide reliable and efficient connection solutions.
