Female Header Double Row 2×40 Pin – 2.54mm Pitch PCB Socket Connector

Overview

The 2×40 Double Row Female Header is an essential PCB connector for creating stackable and modular electronics. With 80 total socket positions in a 2×40 configuration, it provides a high-density interface for connecting modules, sensors, and microcontrollers to a motherboard. Designed with a standard 2.54mm pitch, it ensures 100% compatibility with all standard male headers, jumper wires, and breadboard-friendly components.

Key Features

• Universal 2.54mm (0.1″) Pitch: Fits perfectly on standard perf-boards, stripboards, and professional PCB layouts.

• Low-Profile Design: Keeps your stacked boards close together, ideal for compact enclosures and handheld devices.

• Gold/Tin Plated Contacts: Features high-quality internal leaf springs that maintain a strong electrical connection even after repeated use.

• Cut-to-Length: While slightly more difficult to cut than male headers, these can be trimmed to size (e.g., 2×10, 2×20) using a fine saw or specialized cutters.

• Durable Housing: Made from high-temperature thermoplastic to prevent warping during the soldering process.

Technical Specifications

Common Applications

• Microcontroller Breakouts: Creating sockets for ESP32, Nano, or Teensy boards to allow for easy replacement.

• Display Interfacing: Soldering to the back of 2004 or 1602 LCDs for a removable connection.

• Custom Shields: Building stackable “sandwich” boards for Arduino or Raspberry Pi.

• Internal Interconnects: Connecting two PCBs together via a male-to-female header bridge.
