2-in-1 GLINK / QWIIC / STEMMA QT I2C Breakout Board

The 2-in-1 GLINK I2C Breakout Board is a compact and convenient I2C interface adapter designed for developers, makers, and embedded engineers. It combines a GLINK connector with a 2.54 mm 4-pin header on a single PCB, allowing seamless conversion between GLINK / QWIIC /STEMMA QT cables and traditional breadboard or jumper-wire connections. Documentation for 2-in-1 Glink breakout This board is used as an I2C signal and power breakout, making it ideal for rapid prototyping, debugging, and integrating Glink/QWIIC - compatible sensors and modules into custom or legacy projects. Its small footprint and plug-and-play design simplify I2C wiring while maintaining reliable signal connections. Supported Interfaces: GLINK / QWIIC / STEMMA QT Connector 4-Pin Header (2.54 mm Pitch) 4-Pin Header Definition (2.54 mm): VCC – Power Supply (3.3V / 5V, system dependent) GND – Ground SCL – I2C Clock Line SDA – I2C Data Line Applications I2C signal breakout and conversion GLINK to breadboard interfacing Embedded system development Sensor and module prototyping I2C debugging and testing DIY electronics projects Features Converts GLINK connector to standard 2.54 mm header Supports I2C communication (SCL / SDA) Power and signal breakout on one board Plug-and-play with GLINK/QWIIC/STEMMA QT devices Compact and lightweight PCB design Ideal for rapid prototyping and development
