Questions & answers

Frequently asked questions

These 1x40 female headers use the standard 2.54mm pitch, so they fit common Arduino, Raspberry Pi, ESP32, Arduino shield, PCB, and breadboard layouts designed for 0.1-inch header spacing.
Yes. The 1x40 strip can be trimmed to shorter lengths for custom layouts, replacement sockets, or stackable connections. Cut carefully between pin positions so the remaining header stays aligned with the board footprint.
These are 2.54mm pitch female header pins. They are passive mechanical connectors, not communication modules, so they do not define a protocol, regulate voltage, or convert signals between boards.
They are commonly used to add removable sockets to PCBs, connect Arduino shields, build Raspberry Pi or ESP32 breakout interfaces, and create repeatable plug-in connections for sensors, modules, and prototype wiring.
Check that the module’s male pins use 2.54mm spacing and line up with the header length and orientation. Parts with different pitch, bent pins, or mismatched row spacing will not seat correctly.
