* Support for common temperature sensors (eg, common thermistors,
AD595, AD849x, PT100, MAX6675, MAX31855, MAX31856, MAX31865). Custom
thermistors and custom analog temperature sensors can also be
AD595, AD597, AD849x, PT100, MAX6675, MAX31855, MAX31856, MAX31865).
Custom thermistors and custom analog temperature sensors can also be
configured.
* Basic thermal heater protection enabled by default.
