The 0.100″ (2.54 mm) 2×20-Pin Straight Female Header is a double-row, 40-pin socket strip designed to mate with standard 0.1″ pitch male headers. This is the standard GPIO header size used on Raspberry Pi and other single-board computers, making it an essential connector for SBC projects.

The 2×20 configuration provides 40 pins for full GPIO access, including power, ground, I2C, SPI, UART, and general-purpose I/O lines when used with compatible boards.

Key Features

• 0.1″ (2.54 mm) Pitch – Industry-standard spacing compatible with perfboard and PCBs
• Straight Orientation – Mounts perpendicular to the PCB for standard vertical connections
• 2×20-Pin Configuration – Double-row, 40-position socket matching the Raspberry Pi GPIO layout
• Through-Hole Mounting – Solders directly to standard PCBs

Ideal For

• Raspberry Pi GPIO breakout boards and HATs
• Single-board computer accessories and shields
• Custom PCB designs requiring full 40-pin GPIO access
• Prototyping and board-to-board interconnects
