BTE23-14 I2C Breakout Hub Expander Module 10 Port for Arduino Raspberry Pi

🔗 BTE23-14 I2C Breakout Hub Expander Module – 10-Port I2C Splitter | AuscomTech

The BTE23-14 I2C Breakout Hub Expander Module is a simple and effective solution for expanding a single I2C bus into multiple connection ports without complex wiring.

Designed as a passive I2C distribution hub, this module allows up to 10 I2C devices to be connected in parallel, making it ideal for sensor-heavy projects, rapid prototyping, and clean I2C bus layouts on Arduino, Raspberry Pi, and STM-based systems.

⭐ Key Features

🔢 10-Port I2C Expansion
Splits one I2C bus into 10 parallel ports for easy multi-device connections.

🔌 Plug-and-Play I2C Breakout
No configuration, firmware, or addressing required — simple physical expansion of SDA/SCL lines.

🧩 Wide Platform Compatibility
Works with Arduino, Raspberry Pi, STM32, and other I2C-capable controllers.

📡 Clean & Organised Wiring
Reduces cable clutter and improves reliability compared to daisy-chained wiring.

🧱 Compact PCB Design
Small footprint suitable for embedded systems, robotics, and tight enclosures.
