I2C Switch
Description I2C Switch
The I2C Switch from AB Electronics is a 4-channel bidirectional I2C switch controlled via the I2C bus . It is designed for use on Raspberry Pi boards with a 40-pin GPIO connector. The I2C Switch can be securely mounted to the Raspberry Pi using the mounting kit .
The I2C Switch is based on a PCA9546A controller from NXP. The PCA9546A provides quad bidirectional communication between the I2C port on the Raspberry Pi and all connected I2C devices . Each channel can be enabled or disabled individually. This allows you to connect I2C devices that share the same address to the Raspberry Pi .
The I2C switch is powered by the Raspberry Pi using the GPIO port. Thanks to the extended GPIO pins, you can stack the I2C Switch with other expansion boards.
Each channel operates at either 2.7V - 3.3V or 5V. This allows you to connect I2C devices with different voltages to the Raspberry Pi .
Pull-up resistors should be installed on the SDA and SCL pins of each channel. It is best to use a value between 2.2K and 10K for the pull-up resistors.
The I2C switch supports clock frequencies up to 400 KHz.
