Uses the I2C interface. I2C Address: 0x48 by default (Three additional addresses available, as well). 12-bit, 0.0625°C resolution. Typical temperature accuracy of ±0.5°C.
3.3V sensor. Supports up to four TMP102 sensors on the I2C bus at a time. 2x Qwiic Connectors.
The breakout has built-in 4.7kΩ pull-up resistors for I2C communications and runs from 1.4V to 3.6V..
I2C communication uses an open drain signaling, so there is no need to use level shifting..
The alert pin is an over temperature alert, which has an open-drain and is pulled up through a 10kΩ resistor. The alert can also be read over I2C.

The TCA9548A Breakout board supports communicating with multiple I2C devices with the same address, making it easy to interface with them..
TCA9548A multiplexer features: bidirectional eight-channel I2C multiplexer, active low reset input.
The default address of this expander is 0x70, the address can be changed, and can be set within 0x70~0x77..
In the address of 0x70~0x77, 8 expanders can be cascaded, and each expander can be connected to 8 devices with the same address, so that the same I2C port can be connected to 64 devices with the same address and can be used normally..
The chip is compatible with 3V and 5V and can be used with any logic level.
