## Description

The Gravity I2C Multiplexer solves address conflicts when you need to connect multiple I²C devices that share the same fixed address. It provides eight independent I²C ports on a single bus, allowing up to eight identical-address sensors or modules to communicate without conflict. The default I²C address is 0x70, adjustable via onboard DIP switches from 0x70 to 0x77. By chaining up to eight multiplexers with different addresses, you can theoretically control up to 64 same-address devices on one I²C bus. Key Features 8× Independent I²C Ports – Connect up to 8 same-address devices on one bus Configurable Address – 0x70 to 0x77 via onboard DIP switches 3.3 V and 5 V Compatible – Works with Arduino, Raspberry Pi, and other boards I²C Clock Rates – 100 kHz and 400 kHz Gravity Connector – PH2.0-4P plug-and-play interface (no soldering required) Reset Pin – Active-low reset Dimensions – 32 × 32 mm (1.26 × 1.26 in) Ideal For Multi-sensor arrays with fixed I²C addresses Environmental monitoring with multiple identical sensors Expanding I²C bus capacity in complex projects Resources Product Wiki – Pinout, wiring diagram, and Arduino/Raspberry Pi examples Arduino Library (GitHub)
