Description
The Adafruit STEMMA QT / Qwiic JST-SH 4-Pin Cable is a specialized 4-conductor interconnect designed to link compact 1 mm pitch peripheral modules together quickly and securely. Measuring just over 100 mm (4 inches) in length, this symmetrical cable features latching 1 mm pitch JST-SH female connectors on both ends, allowing rapid, polarized, and latching plug-and-play connections without the need for soldering or breadboards.
Engineered for modular prototyping ecosystems, the cable utilizes standard color-coded wiring (Red for 3.3VDC power, Black for Ground, Blue for I2C SDA data, and Yellow for I2C SCL clock) to prevent wiring errors. Built symmetrically so orientation does not matter, it provides a reliable bridge for daisy-chaining advanced STEMMA QT, Qwiic, and I2C sensor boards.

Key Features
- Dual Latching JST-SH Connectors: Equipped with secure 1 mm pitch 4-pin JST-SH female connectors on both ends with a tactile latching feel.
- Optimal 100 mm Reach: Provides an ideal ~10 cm length for positioning compact Qwiic and STEMMA QT modules close together within enclosures.
- Symmetrical Design: Reversible layout ensures either end can be plugged into any compatible board without orientation concerns.
- Standardized Color Coding: Color-coded conductors (Red for 3.3V, Black for GND, Blue for SDA, Yellow for SCL) offer clear visual tracking.
- Flexible & Lightweight Build: Thin, highly flexible wiring minimizes mechanical strain on delicate peripheral connector ports.
Benefits
- Solder-Free Efficiency: Eliminates manual wire stripping, crimping, and soldering, enabling instant modular circuit assembly.
- Error-Proof Interfacing: Keyed JST-SH connectors ensure correct pin alignment every time, protecting sensitive I2C hardware from damage.
- Optimized Prototyping Reach: Perfect for daisy-chaining adjacent sensors or connecting peripheral boards mounted close to each other.
- Reusable Interconnect: Designed to withstand repeated plugging and unplugging cycles in active testing and development labs.
- Ecosystem Versatility: Fully compatible with Adafruit STEMMA QT, SparkFun Qwiic, and other standardized 1mm JST-SH peripheral modules.
Applications
- I2C Sensor Daisy-Chaining: Connecting multiple STEMMA QT or Qwiic environmental, motion, and optical sensors in series.
- Modular Robotics: Routing data and power lines between distributed control boards and peripheral modules across a compact chassis.
- Prototyping & Test Rigs: Providing quick, temporary signal links between development boards during hardware debugging phases.
- Enclosure Integration: Linking internal control boards to nearby front-panel displays or modular sensor units.
- Educational Electronics: Simplifying multi-sensor wiring for students and makers learning digital communication protocols.
