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 and the PMSA003I Air Quality Breakout, 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.

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

- 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)
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- SWD
- Serial Wire Debug is a two-wire programming and debugging interface used with many microcontrollers. It matters if you need low-level access to program, recover or debug the processor board connected to this carrier.
