OSEPP I²C Expansion Shield

The OSEPP I²C Expansion Shield is an Arduino-Compatible daughter (extension) card. It provides easy interconnection with other I²C devices, such as the OSEPP Sensor Modules family. As well, it integrates an I²C switch 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 bus are brought out to a robust latchable 4-pin connector that allow easy plug and play functionality.
