JST Male Connector 2.0mm (3-Pin) (Straight)

Overview

The JST 2.0mm 3-Pin Male Connector is a compact PCB-mounted wire-to-board header used for reliable signal and low-power DC connections in electronics, robotics, drones, Arduino/ESP32 projects, sensors, and battery systems. It belongs to the JST PH series (2.0mm pitch), which is widely used in compact embedded designs requiring stable multi-line connectivity.

This connector is available in straight (vertical) version, allowing flexible PCB layout and enclosure design.

How JST 2.0mm 3-Pin Male Connector Works

The connector functions as a board-to-wire interface:

• Male header pins are soldered onto a PCB
• A matching JST PH 3-pin female housing (crimped wires) plugs into it
• The keyed design ensures correct orientation and prevents reverse connection
• Each pin carries a dedicated electrical path (signal/power/ground)

Straight Version Benefits

Straight versions are used for:

• Vertical cable connection
• Open-space PCB layouts

Applications

• Arduino and ESP32 development boards
• Drone and RC electronics
• Sensor modules and signal wiring
• Battery-powered devices (1S LiPo systems)
• Robotics and automation systems
• PCB prototyping and embedded electronics

Advantages of JST PH Male Connectors

• Compact and space-saving 2.0mm design
• Reliable locking and stable connection
• Suitable for multi-signal wiring
• Easy PCB integration via soldering
• Widely used standardized connector system

Usage Tips

• Always match with JST PH 2.0mm female housing
• Verify correct pin orientation before soldering
• Use right-angle version for tight enclosure designs
• Avoid forcing connector insertion to prevent damage
• Ensure proper solder joints for mechanical strength
