From the project

Raspberry Pi Thermocouple pHat

The Raspberry Pi Zero sized Hats are now officially called Micro-Hats or uHats but for consistency sake, this board's name will remain Raspberry Pi Thermocouple pHat.

This is a Raspberry Pi Micro-Hat PCB that supports:

Three MAX31850 1-Wire Thermocouple Converters for remote temperature sensing DS18S20 1-Wire Thermometer for local Hat temperature * Magnetic Buzzer/Alert
