The SparkFun TMP102 Qwiic breakout provides accurate digital temperature readings over I2C with minimal wiring. Based on the Texas Instruments TMP102, the sensor delivers 0.0625 °C resolution and ±0.5 °C accuracy, communicating entirely over the I2C bus — no analogue conversion needed.

This version features two Qwiic connectors for plug-and-play I2C daisy-chaining, an address jumper for multi-sensor setups, and standard 0.1" header breakouts for breadboard use. Built-in 4.7 kΩ pull-up resistors and open-drain I2C signalling mean no level shifting is required.
