Product details
The 4-in-1 GLINK / QWIIC / STEMMA QT Connector Board is a compact interconnect module designed to simplify I²C signal distribution in embedded and prototyping systems. It allows a single GLINK connection to be split into multiple ports, enabling easy daisy-chaining of GLINK/Qwiic-compatible sensors, displays, and peripherals without soldering or complex wiring.
This board provides four GLINK connectors arranged in a cross layout, ensuring clean signal routing and reliable power distribution across all connected devices. It supports standard GLINK / STEMMA QT / QWIIC I²C signals (3.3V, GND, SDA, SCL) and is fully compatible with popular development platforms such as Arduino, GLYPH and other microcontrollers using QWIIC or STEMMA QT ecosystems.
Commonly used as an I²C hub or splitter, the 4-in-1 QWIIC connector board is ideal for rapid prototyping, sensor expansion, and modular system design. Its small footprint, plug-and-play operation, and robust PCB design make it well suited for educational kits, IoT devices, and compact embedded projects
