An I2C splitter/mux based on the PCA9548A chip. This chip has one I2C input, and 8 outputs whcih can be connected to or disconnected from the main I2C bus.

Possible uses:
- Connecting multiple devices with the same address to one bus
- Disconnecting part(s) of the I2C bus


The board can be used with all microcontrollers, such as the Atmel AVR, Arduino/Freeduino boards, Microchip PIC, etcetera. Other computers/boards with an I2C interface (such as the Raspberry Pi) should also be able to control this module.
 

The module comes with all connectors pre-soldered

The PCA9548A chip is sold by NXP and TI and can be used interchanably.
