I²C Expansion Shield for Arduino

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.

Specifications:

• I²C Addresses (7-bit) 0x70, 0x71, 0x72, 0x73, 0x74, 0x75, 0x76, 0x77
• Form Factor 53.3 mm x 68.6 mm
• Power Consumption 0.1 mW
• Connector Pin Definition 
• Pin 1: Power
• Pin 2: I2C Data
• Pin 3: Ground
• Pin 4: I2C Clock

Features:

• 1-to-4 I²C switch to provide four isolated I²C buses
• Stackable with other Arduino and Arduino Compatible shields
• Provides pass through of all I/O as well as reset button and ICSP connector.
• Three selectable address bits for I²C switch to allow stacking of up to eight Shields
• Supports boards with the Arduino Shield interface, such as (but not limited to):
• Duemilanove • Uno • Pro • Bluetooth • Mega/Mega 2560
• Works with 3.3 V and 5 V boards
• Plug and play I²C connectors that provide I²C, power, and ground signals
