Gravity: Digital 1-to-8 I2C Multiplexer
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)
