2.54mm 1×40 Pin Male Single Row Straight Short Header Strip (Pack of 5)

It is a 2.54mm 1×40 Pin Male Single Row Straight Short Header Strip. It has one row of 40 pins. Ideal for through-hole mounting. It has 11.5mm short pins and the plastic spacer can be adjusted according to the application.

A 2.54mm 1×40 Pin Male Single Row Straight Short Header Strip is a fundamental electronic component with widespread applications in circuit board assembly, prototyping, and interfacing. This particular header strip features a standard pitch of 2.54mm (0.1 inches), one row of 40 pins, and a straight, short design. Despite its seemingly simple appearance, this component plays a crucial role in facilitating electrical connections within electronic systems and devices.

The 2.54mm pitch refers to the distance between adjacent pins, making it compatible with standard perforated prototyping boards, breadboards, and through-hole PCBs. This standardized pitch ensures compatibility and interchangeability with a wide range of electronic components, allowing for seamless integration into various circuit designs.

The 1×40 configuration denotes a single row of 40 pins, arranged linearly. This layout provides a convenient interface for connecting electronic modules, sensors, ICs (integrated circuits), and other peripherals to a main circuit board or microcontroller. The 40-pin count offers ample connectivity options for transmitting power, signals, and data linearly between different components, enabling complex circuitry and functionality.

The male designation indicates that the pins protrude outward from the header strip, allowing for insertion into corresponding female connectors or receptacles. This configuration ensures secure and reliable electrical connections, essential for maintaining signal integrity and preventing accidental disconnections in electronic systems.

The straight, short design of the header strip refers to the orientation and length of the pins. In this configuration, the pins are aligned in a straight line perpendicular to the header strip’s base, facilitating easy insertion into circuit boards or sockets. The short length of the pins minimizes the risk of interference with nearby components or traces on the PCB (printed circuit board), making it suitable for compact and densely populated layouts.

The versatility of the 2.54mm 1×40 Pin Male Single Row Straight Short Header Strip makes it indispensable in various electronic projects and applications. In prototyping and experimentation, it serves as a convenient interface for connecting development boards, sensors, actuators, and other electronic modules to breadboards or perf boards. This allows engineers, hobbyists, and students to quickly iterate and test circuit designs, troubleshoot issues, and develop prototypes without the need for soldering or permanent connections.

In circuit board assembly and production, header strips are commonly used to create standardized connectors for interfacing with peripheral devices or expansion modules. By soldering the header strip to a PCB, manufacturers can establish reliable electrical connections between the main circuit board and external components, such as displays, connectors, or expansion cards. This modular approach simplifies assembly, maintenance, and upgrades, as components can be easily added, removed, or replaced as needed.

Additionally, header strips play a crucial role in creating programming and debugging interfaces for microcontrollers, development boards, and embedded systems. By connecting a header strip to the programming port or debug interface of a device, engineers and developers can upload firmware, debug code, and perform diagnostic tests using dedicated programming tools, such as USB programmers, JTAG (Joint Test Action Group) adapters, or UART (Universal Asynchronous Receiver-Transmitter) converters. This capability is essential for firmware development, software debugging, and system validation throughout the product development lifecycle.

Furthermore, header strips are utilized in various electronic subsystems and modules, including motor drivers, sensor arrays, communication interfaces, and power distribution boards. By providing standardized connectors and interconnectivity options, header strips enable modular design architectures, interoperability between different subsystems, and scalability for future upgrades or expansions.
