This 2×20-pin right-angle female header with 0.1" (2.54mm) pitch provides a convenient way to add right-angle connectivity to circuit boards with dual-row 40-pin headers. It mates with standard 2×20 dual male headers for easy board-to-board or board-to-cable connections.
The right-angle orientation is useful when vertical clearance is limited or when you need to route connections parallel to the PCB surface, making it a practical choice for Raspberry Pi GPIO and similar 40-pin interfaces.
Key Features
- 2×20-Pin (40 pins total) – Matches standard 40-pin dual-row headers
- Right-Angle Orientation – Routes connections parallel to the board surface
- 0.1" (2.54mm) Pitch – Industry-standard spacing for broad compatibility
- Female Contacts – Mates with standard male header pins
Ideal For
- Raspberry Pi GPIO connections in low-clearance enclosures
- Board-to-board connections requiring right-angle orientation
- Prototyping with 40-pin dual-row interfaces
Package Contents
- 1× 2×20-pin right-angle female header
Jargon buster
Plain-language definitions for the technical terms used above.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
