SparkFun MAX31855K Thermocouple Breakout Arduino Library

MAX31855K Thermocouple Breakout


This library is used for interfacing the SparkFun MAX31855K Thermocouple Breakout board. The library is configured by default to interface the board on pins D10-A1 of a 3.3V Arduino Pro Mini. The pins are configurable in the sketch, but this board runs at 3.3V. Level shifting is needed if you are not using a 3.3V device to communicate with it.
