JST Male Connector 2.0mm (4-Pin) (Straight)

The JST 2.0mm 4-Pin Male Connector is a standard PCB-mounted wire-to-board header used in compact electronic systems for reliable signal and low-power DC connections. It belongs to the JST PH series (2.0mm pitch), which is widely used in Arduino, ESP32, drones, robotics, battery systems, and sensor modules due to its small size and secure locking mechanism.

This connector is available in straight (vertical) configuration to support different PCB layout requirements.

How JST 4-Pin Male Connector Works

The connector acts as a wire-to-board interface system:

• Male header pins are soldered onto a PCB
• A matching JST PH 4-pin female housing (crimped wires) connects to it
• The keyed design ensures correct orientation and prevents reverse insertion
• Each of the 4 pins carries a separate electrical path (power or signal lines)

When to Use Straight JST Connectors

• Vertical cable connection is preferred
• PCB has sufficient vertical clearance

Applications of JST 2.0mm 4-Pin Connectors

• Arduino and ESP32 development boards
• Robotics and automation systems
• Drone electronics and flight controllers
• Sensor and module connections
• Battery-powered devices (1S LiPo systems)
• PCB prototyping and embedded electronics

Advantages of JST PH 4-Pin Male Headers

• Compact 2.0mm pitch saves PCB space
• Secure and vibration-resistant connection
• Easy integration into standard PCB designs
• Widely used industry-standard connector
• Prevents misconnection due to keyed housing

Usage Tips for JST Male Connectors

• Always match with JST PH 2.0mm female connector
• Verify pin orientation before soldering
• Use right-angle type for tight enclosures
• Avoid forcing connectors during mating
• Ensure strong solder joints for durability
