Modulino Extender I2C signal extension module, LTC4311 bus accelerator, Qwiic interface, supports long-distance communication.

Long-distance communication extension module

I2C signal enhancement, supporting longer cable connections.

The Modulino™ Extender is a communication extension module based on the LTC4311 I2C signal accelerator, designed specifically to extend the I2C bus communication distance. By enhancing I2C signal quality, it can achieve long-distance communication of up to approximately 30 meters at a 100 kHz communication rate when used with CAT5e/CAT6 network cables. It is suitable for remote sensor networks, distributed devices, and IoT applications.

The module uses a purely hardware-based design, requiring no additional configuration or dedicated driver library installation. It is equipped with a Qwiic interface, allowing convenient connection to Arduino development boards and Modulino™ series modules for flexible and reliable I2C communication extension.

Product features

Long-distance I2C communication: supports a communication distance of up to approximately 30 meters (at 100 kHz under recommended cable conditions), breaking through the short-distance connection limitation of conventional I2C.
LTC4311 signal enhancement: built-in I2C bus accelerator improves signal rising edges and enhances long-cable communication reliability.
Configuration-free plug-and-play: purely hardware-based operation, requiring no additional drivers or dedicated software libraries.
Qwiic standard interface: supports quick connection to Arduino development boards and other Qwiic-compatible devices.
Compatible with the Modulino™ ecosystem: can be paired with a variety of Modulino™ sensor and actuator modules to flexibly build distributed applications.
Compact and lightweight: easy to integrate into IoT devices, remote sensors, and embedded projects.
