Gravity: LTC4316 I2C Address Shifter Module

SKU: DFR1193

The DFRobot Gravity I2C Address Shifter changes I2C sensor addresses. Connect it between your dev board and sensor for plug-and-play, compact integration. Get 4 addresses via on-board dip switches, plus 20+ more by soldering resistors. It solves same-address sensor issues without code port switching or timing bugs. Note: no clock extension (not for BNO055); know how to adjust sensor addresses in code first.
