What is it?

A temperature sensor board built around the TMP117, compatible with SparkFun's quiic system.

• small: 8.5 x 10 mm
• accurate: The TMP117 has
• +/- 0.1 K (typ) over the whole -50° to 150° C temperature range
• +/- 0.05 K (typ) between -40 to 70° C
• this board does not use the less accurate "M" or "N" variant
• ADD0 input configurable with a solder jumper
• ALERT output to an LED and a testpoint if you need it externally
• JST SH connector, quiic-compatible pinout
• 1 mm aluminium PCB
• no on-board voltage regulator and level shifting: you can only use it in 3V3 systems!

Important: If you get the variant without ADD0 pre-configured, you'll have to add the solder bridge yourself to configure the sensor's I2C address.

Why did you make it?

I needed a small and easy to use temperature sensor board.

What makes it special?

The small aluminium PCB makes it well suited for applications where you need low thermal resistance that integrates well into your existing prototyping environment.
