## Description

The DFRobot I2C Address Shifter is designed to modify the I2C address of connected sensors for [Arduino](https://www.dfrobot.com/topic-277.html), [Raspberry Pi](https://core-electronics.com.au/raspberry-pi.html), and other [development boards](https://www.dfrobot.com/category-184.html). By inserting this module between the host board (such as an Uno R3 or Pi 4) and an I2C sensor, identical sensors can operate simultaneously on the same bus. The plug-and-play module features a compact design for easy integration into I2C cascading systems, with four switch-selectable addresses and over 20 additional options via resistor soldering.

**Plug-and-Play Hardware Solution**

The I2C Address Shifter eliminates the need for software-based port switching, simplifying system integration. Address conversion occurs entirely within the module, ensuring compatibility without modifying existing code or risking I2C timing conflicts.

**Flexible Address Configuration**

With four address options accessible via DIP switches and expandable options through resistor soldering, the module supports diverse addressing requirements. This flexibility allows users to deploy multiple identical sensors on a single I2C bus effortlessly.

**Compact and Universal Compatibility**

The module’s small form factor and broad compatibility with I2C sensors make it ideal for space-constrained projects. It seamlessly integrates into existing setups without requiring additional hardware adjustments.
