The RTD Click Board™ is based on MAX31865 resistance to digital converter from Maxim Integrated, optimised for platinum resistance temperature detectors, or RTD. The Click Board™ uses the PT100-type platinum probe for temperature measurement. There are four screw terminals on the board, so different PT100 probe types can be used with this design.
This RTD Click Board™ can work with 2, 3 or 4-wire PT100 probe types.
