## AI Product Insights

This **0.05" (1.27mm) pitch female socket header** is a 2×5 (10-pin) through-hole connector designed for fine-pitch applications. Originally sourced as the mating connector for the [PMSA003I Air Quality Sensor](https://littlebirdelectronics.com.au/products/pm2-5-air-quality-sensor-with-i2c-interface-pmsa003i) and the [PMSA003I Air Quality Breakout](https://littlebirdelectronics.com.au/products/adafruit-pmsa003i-air-quality-breakout-stemma-qt-qwiic), it's now available on its own for custom PCB projects.

The **1.27mm pin spacing** is half the standard 2.54mm pitch, making it suitable for compact board designs where space is at a premium. The header is primarily designed for through-hole soldering, but the flat pins can be bent outward for surface-mount (SMT) applications if needed.

This connector also matches the standard **SWD (Serial Wire Debug) pinout**, so it's a handy part to have for debugging ARM-based microcontrollers like those found in STM32, nRF52, and RP2040 boards. If you're designing a custom PCB that needs a compact 10-pin debug header or sensor connector, this is the part you're after.

### Key Features

## Description

A compact 0.05" pitch (1.27mm) thru-hole female socket header in a 2×5 (10-pin) configuration. Originally designed for use with the PM2.5 Air Quality Sensor (PMSA003I) and its breakout board, this header is also handy for your own sensor and prototyping projects. These headers match standard SWD (Serial Wire Debug) connectors, making them useful for debugging ARM-based microcontrollers. Although designed for through-hole mounting, the flat pins can be bent outward for surface-mount (SMT) use. Key Features 0.05" (1.27mm) Pitch – Fine-pitch spacing for compact board designs 2×5 Configuration – 10 pins total in a dual-row layout Through-Hole Mounting – Solder directly into your PCB; pins can be bent for SMT use SWD Compatible – Matches standard SWD debug connector pinouts Ideal For Air quality sensor breakout boards (e.g. PMSA003I) SWD debugging connections on ARM microcontrollers Custom PCB prototyping with fine-pitch connectors Package Contents 1× 0.05" Pitch Thru-Hole Female Socket Header (2×5, 10-pin)
