I2C Digital Interface Module: Expanding Smart Home Connectivity
The I2C Digital Interface Module by SIMO.io enables seamless communication between your Game Changer controller board and a wide range of I2C-compatible digital devices. This module is designed to open up endless possibilities for adding smart sensors and controllers to your home automation system, allowing you to connect and control even more devices.
TL;DR
- Magnetically isolated I2C interface (GND, +5 V, SCL, SDA).
- Use CAT5/UTP; always twist SCL with GND and SDA with GND (field‑tested to ~20 m).
- One I2C line can host many devices (addresses permitting); keep runs practical.
Key Features:
-
Magnetically Isolated I2C Connection: The module provides a magnetically isolated I2C interface to your controller board, ensuring safe, interference-free communication between devices. This isolation helps protect your system from potential electrical noise or surges.
-
Simple 4-Terminal Layout: With 4 terminals for easy connections—GND, +5V, SCL, and SDA—you can quickly integrate compatible devices into your smart home system.
-
Wide Range of Supported Devices: The I2C Digital Interface Module allows you to connect a variety of digital devices that use the I2C protocol, including:
- Light Sensors
- Temperature Sensors
- Humidity Sensors
- Air Quality Sensors
- Other Controllers and Modules
Whether you're monitoring environmental conditions or integrating specialized controllers, this module expands your system’s reach, giving you even more control and insight into your home.
-
Growing Device Compatibility: We’re constantly updating and expanding the list of supported I2C devices. We also invite our customers to share their feedback on which I2C devices they’d like to see supported in the future, helping us shape a smart home ecosystem tailored to your needs.

Wiring Tip
The I2C communication protocol is generally not designed for long-distance communication, but we've discovered a way to significantly extend cable lengths by using standard CAT5 or higher UTP cable. We have successfully installed various sensors across multiple smart home systems using this wiring scheme:
- SCL → Green
- SDA → Blue
- +5V → White/Orange
- GND → White/Green and White/Blue
The most important part is that SCL and SDA lines must be paired with GND to protect them from interference. This setup leaves you with three free wires, which we sometimes use to connect a 12V sensor, such as a motion sensor or smoke detector. In this case, we use the Orange wire to transmit +12V, while the Brown pair is used to carry the sensor signal itself.
Using a regular CAT5 UTP cable in a careful and sensible manner allows for extended I2C communication distances, with the added benefit of being able to connect additional sensors.
Change the module, not your weekend
Every SIMO.io PCIe‑style module is field‑replaceable. Your logic is bound to the port—not to throwaway device IDs—so if a module ever fails or you’re upgrading, pull it off the rail, snap in the replacement, and you’re done. The Game Changer board provides the same signals over that PCIe port instantly, so scenes, schedules, and security rules stay intact. No re‑pairing. No reprogramming. No hunting through automations. Keep a small set of spares and restore full function in minutes. That’s professional serviceability by design.
SIMO.io — Smart Home Supremacy. Every module serves with quiet precision—ruled locally by The Game Changer board, commanded by your SIMO.io hub (local or virtual)—for protective, reliable, inevitable control.
