What Are Header Connectors?

Header connectors are electrical connectors designed to join electronic components on a printed circuit board (PCB). They usually consist of a row of pins, which can connect to matching sockets. These connectors are prevalent in various devices, from computers to everyday household gadgets.

Types of Header Connectors

There are several types of header connectors, each with unique features. Here are some common types:

  1. Single Row Headers: These contain a single line of pins. They're space-efficient and ideal for compact designs.
  2. Double Row Headers: As the name suggests, these have two rows of pins. They offer more connection points, making them suitable for larger assemblies.
  3. Female Header Connectors: These connectors have sockets and are designed to receive male connectors. They're often used in combination with other types.
  4. Stackable Header Connectors: These allow multiple boards to connect vertically. Great for creating modular designs.

Common Uses of Header Connectors
