The Duet supports up to two MAX31865-based daughter boards. Each daughter board supports two PT100 temperature sensors or thermocouples.

A Temperature Daughterboard may be desired if, for example, you wish to print with materials which require greater than 290°C, which is the limit for a thermistor.

A Temperature Daughterboard allows the Duet to connect with a thermocouple or PT100 temperature sensor, which send a different type of signal than a thermistor.

If you plan to use PT100 temperature senesors, please read the wiki regarding the use of Temperature Daughterboards.
