This is a breakout board for the tiny Texas Instruments TMP102 digital temperature sensor. The TMP102 uses I2C/TWI, has a resolution of 0.0625°C, and is accurate up to 0.5°C. The sensor requires very low current, and is loaded with features.

Communication with the TMP102 is achieved through a two-wire serial interface. There is no on-board voltage regulator, so supplied voltage should be between 1.4V to 3.6V DC. Filtering capacitors and pull-up resistors are included as shown.
