DFR1193

DFR1193 is a Gravity: I2C Address Shifter - I2C conflict resolver board for Arduino & Raspberry Pi. The DFRobot I2C address shifter is designed to modify the I2C address of connected sensors for Arduino, Raspberry Pi, and other development boards. 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. Suitable for sensor arrays: deploying multiple identical sensors (e.g., light, temperature) in IoT or agricultural monitoring systems, robotics: enabling obstacle-avoidance robots with redundant TOF sensors on a single I²C bus. Industrial automation: streamlining production line setups with address-conflict-free sensor networks.
