Adafruit STEMMA QT / Qwiic JST-SH 4-Pin to Premium Male Headers Cable | 150 mm Length 1 mm Pitch to 2.54mm Male Header Interconnect for Breadboards & Microcontrollers (Single Unit)

Description

The Adafruit STEMMA QT / Qwiic JST-SH to Premium Male Headers Cable is a specialized 4-conductor conversion interconnect designed to bridge compact 1 mm pitch peripheral modules directly with standard experimental breadboards and microcontroller header pins. Spanning slightly over 150 mm (6 inches) in length, this adapter cable features a latching 1 mm pitch JST-SH female connector on one end and individual premium male header pins on the other, allowing seamless integration without requiring custom soldering.

Engineered for modular electronics ecosystems, the cable utilizes flexible color-coded wiring (Red for 3.3VDC power, Black for Ground, Blue for I2C SDA data, and Yellow for I2C SCL clock) to ensure error-free power and communication routing. It provides a reliable bridge for connecting advanced STEMMA QT, Qwiic, and I2C sensor boards to traditional development platforms like Arduino, ESP32, and Raspberry Pi.

Key Features

• Hybrid Conversion Design: Features a latching 1 mm pitch JST-SH female connector on one end and 4 individual premium male header pins on the opposing end.
• Optimal 150 mm Reach: Provides an ideal ~15 cm length for routing signals between compact modular boards and nearby breadboard rails or controller sockets.
• Standardized Color Coding: Color-coded conductors (Red for 3.3V, Black for GND, Blue for SDA, Yellow for SCL) ensure clear visual tracking.
• Standard 2.54mm (0.1 in) Pitch Pins: Premium male terminals mate securely with standard breadboard tie-points and female header sockets.
• Compact JST-SH Interface: Utilizes fine 1 mm pitch connectors with a secure latching feel while remaining easy to insert and remove.

Benefits

• Solder-Free Prototyping: Enables instant connection of STEMMA QT and Qwiic sensors directly to experimental breadboards and development board headers.
• Cross-Platform Compatibility: Expands the usability of compact I2C peripheral modules to standard microcontrollers lacking native JST ports.
• Error-Proof Wiring: Standardized pin arrangement and color-coding prevent accidental miswiring of power and communication lines.
• Reusable Interconnect: Designed to withstand repeated plugging and unplugging cycles in active testing and development labs.
• Versatile Termination: Allows direct insertion into breadboards, connection to 0.1-inch socket headers, or permanent soldering to custom pads.

Applications

• Breadboard Sensor Testing: Connecting STEMMA QT or Qwiic-enabled environmental, motion, and optical sensors directly to standard breadboard circuits.
• Microcontroller Interfacing: Linking compact peripheral modules to Arduino, ESP32, or Raspberry Pi development pins via male header pigtails.
• Prototyping & Test Rigs: Providing quick, temporary signal links during hardware debugging and diagnostic testing phases.
• Custom Enclosure Wiring: Bridging internal JST-connected components to main control boards mounted on standard header pins.
• Educational Electronics: Simplifying multi-sensor wiring for students and makers learning digital communication and I2C protocols.

Package Includes

• 1 x Adafruit STEMMA QT / Qwiic JST-SH 4-Pin to Premium Male Headers Cable (150 mm)
