JST Male Connector 2.54mm (3-Pin) Overview
The JST Male Connector 2.54mm (3-Pin) is a compact, reliable wire-to-board connector designed for secure electrical connections in electronics projects. With a standard 2.54mm pitch and three contacts, it reliably carries power, ground and signal lines in a small footprint for hobbyist and commercial applications.
Straight and Right-Angle Variants
Choose between straight and right-angle mounting depending on board layout and space constraints:
- Straight: Ideal for vertical header mounting on PCBs where cables connect from above.
- Right-Angle: Perfect for edge connections or horizontal routing to keep wiring neat in compact enclosures.

- Pin count: 3-pin for power, ground and signal
- Pitch: 2.54mm (standard spacing compatible with many headers and perfboards)
- Construction: Durable plastic housing with corrosion-resistant metal contacts
- Compact and lightweight design for tight spaces
- Secure mating and reliable electrical contact for long service life
Specifications
- Connector family: JST
- Contact material: Tin or nickel-plated metal (corrosion-resistant)
- Housing material: High-quality plastic
- Mounting styles: Through-hole or surface mount variants available depending on model
- Typical uses: PCB headers, wiring harnesses, and custom cable assemblies
Applications
This 2.54mm 3-pin JST male connector is widely used across electronics projects and products, including:
- Arduino shields and breadboard prototyping
- Robotics and automation systems
- RC models, drones and battery connections
- Sensors, modules and small embedded systems
- Custom wiring harnesses and repair work
Installation and Compatibility Tips
- Verify the mating female housing or PCB footprint matches a 2.54mm pitch and 3-pin layout.
- Use the straight variant for vertical connections; use the right-angle variant for edge or horizontal routing.
- Crimp or solder wires according to recommended practices to ensure reliable contact and strain relief.
- Inspect contacts for secure fit and avoid excessive force when mating connectors.
