Pinouts of TMP117 temperature sensor
The sensor can be connected in two ways. The first is via the solder pads, to which agoldpinstrip with a 2.54 mm pitch must be soldered. Alternatively, the sensor is also equipped withSTEMMA QT /Qwiicconnector, which allows for quick and convenient connection of the module without soldering. The picture on the right shows how to connect the sensor using STEMMA QT / Qwiic connector and Metro board -equivalent of popular Arduino board.
