A Python library for controlling the Interface Expander device

USB Interface Expander

interface-expander is a lightweight Python library that allows you to communicate with USB Interface Expander devices.
It provides a simple API for interacting with I²C peripherals and controlling analog outputs (±12 V, 2-channels) directly from Python.

🧩 Features

• USB → I²C bridge — communicate with I²C sensors and devices from your PC
• USB → ±12 V DAC output — set precise analog voltages from Python
• Cross-platform — works on Windows, macOS, and Linux
• Plug-and-play — automatically detects connected Interface Expander devices (no additional drivers needed)

🚀 Getting Started
