The OSEPP I²C Expansion Shield is an Arduino-compatible daughter (extension) card. This shield provides easy interconnection with other I²C devices, such as the OSEPP Sensor Modules family.
Additionally, this shield integrates the PCA9546A I²C switch from Texas Instruments that provides 4 additional isolated I²C buses to enable the use without collisions of multiple I²C devices with same I²C addresses. The main I²C bus and each of the 4 additional I²C buses are brought out to a robust latchable 4-pin connector that allow easy plug and play functionality.
- 100% Arduino compatible.
- 1-to-4 I²C switch to provide four isolated I²C buses.
- Provides pass through of all Arduino I/O, reset button and ICSP connector.
- Stackable with up to eight other Arduino shields.
- Works with both 3.3V and 5V boards.
