      • Fully Differential VREF Inputs • 21ms (max) Conversion Time 
      • Integrated Fault Detection Increases System Reliability 
      • ±45V Input Protection • Fault Detection (Open RTD Element, RTD Shorted to Out-of-Range Voltage, or Short Across RTD Element)
 
Thermocouple amplifiers are great for applications requiring extreme temperatures - but thermocouples don't have the best accuracy or precision, for when the readings must be as good as can be. The MAX31865 handles all of your RTD needs and can even compensate 3 or 4 wire RTDs for better accuracy. Connect to it with any 3.3V microcontroller over SPI and read out the resistance ratio from the internal ADC. We put a 400Ω 0.1% resistor as a reference resistor on the breakout. 
 
 
Please note that required 3.3V Raspberry Pi 3/4 or Arduino NANO BLE 33 and the 2/3/4 wire RTD100 Temperature probes must be provided by the user or purchased separately.
 
Please note that this is a low power 3.3V version designed to work specifically with the Raspberry Pi 3/4 and Arduino NANO BLE 33 and Arduino H7 microcontrollers and requires partial assembly of soldering pin headers and two screw terminals to the PCB board. It cannot be connected to 5.0V devices.
