Soldering iron thermometer shield for Arduino

Thermocouple Arduino shield that measures the temperature of a soldering iron. We recommend it for people who are having a hard time soldering, or want to know the temperature of the iron.

The I/O voltage correspond to both 3.3 V and 5 V Arduino shields.

How to use:Please refer to (Sorry only in Japanese)

Pin header is not included.
