The TMP119 is the most precise-iest temperature sensor ever? 🌡️

Small green circuit board labeled TMP119 Precision Temperature Sensor with Stemma QT connectors on each side, displayed at an angle against a colorful blue and purple abstract gradient background

New year, new proto! We’re getting our pants on (metaphorically) and here’s a first new proto to kick things off 🎉

The TMP119 has ±0.03°C (typical) accuracy from 0°C to 45°C…that’s wild precision for a little breakout board. It’s very much like our existing TMP117, so we just tweaked the PCB for this teeny DSBGA-8 footprint.

We’re going to see how hard it is to pick & place this tiny part, but it was requested and it looks pretty nifty! As always, it’s got our Stemma QT connectors on board for easy I2C daisy-chaining.
