Product Description
The JST XH 2.54mm 4-Pin Male Connector Header is a reliable through-hole mounting connector designed for secure, polarized wire-to-board connections in electronic projects and power circuits. Featuring a standard 2.54mm pitch spacing—matching typical breadboard and header pin spacing—and a robust shrouded housing, it ensures secure mating with matching JST XH female cable assemblies while preventing reverse polarity insertion.
Essential for microcontroller power lines, stepper motor connections, balance charging leads, and peripheral sensor wiring, this header solders cleanly onto printed circuit boards for durable four-conductor electrical connections.
⚠️ Polarity & Pinout Tip: Always verify your circuit’s exact pin assignment (such as power, ground, and data signals) against your mating cable before powering on your devices to prevent accidental short circuits or reverse-voltage damage.
Technical & Architectural Highlights
