OSEPP™ I²C Expansion Shield


Bookmark and Share
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.

• I²C Addresses (7-bit): 0×70, 0×71, 0×72, 0×73, 0×74, 0×75, 0×76, 0×77
• 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


  • 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
