A 2×3-pin (6-pin) female header with standard 0.1" (2.54mm) spacing. This compact dual-row header is commonly used for ISP programming connections, small sensor breakouts, and custom cable assemblies.
The 2×3 configuration matches the standard AVR ISP programming header pinout, making it essential for Arduino bootloader programming and AVR development.
Key Features
- Standard 0.1" Pitch – Compatible with breadboards and perfboard
- Dual Row – 2×3 pin configuration (6 pins total)
- Through-Hole Mount – Solder directly to PCBs
- Low Profile – Compact connector for space-constrained projects
Ideal For
- AVR ISP programming headers
- Arduino bootloader programming
- Custom cable connectors
- Sensor and module connections
- Prototyping on perfboard
Specifications
- Pins: 6 (2 rows × 3 pins)
- Pitch: 2.54mm (0.1")
- Type: Female socket
- Mounting: Through-hole
Package Contents
- 1× 2×3-Pin Female Header
Jargon buster
Plain-language definitions for the technical terms used above.
- AVR
- AVR is a family of 8-bit microcontrollers (made by Microchip, formerly Atmel) used in many classic Arduino-style boards such as the Uno and Nano. They are widely supported but older, which can be a limit for memory- or speed-intensive tasks.
- Bootloader
- Small starter software on a microcontroller that lets new code be uploaded before the main program runs. Knowing how to enter bootloader mode matters when you need to program the board or recover it after a faulty sketch.
- 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.
- ISP
- In electronics, ISP usually means In-System Programming, a way to load firmware onto a microcontroller while it stays on the board (often via an ICSP header), or an Image Signal Processor, hardware that turns raw camera sensor data into usable images and offloads the main CPU. The surrounding context shows which meaning applies.
- through-hole
- A mounting style where the component leads pass through holes in a circuit board and are soldered on the other side. Through-hole parts are often easier to handle and solder by hand, which is useful for classroom and hobby projects.
