The MAX31865 module communicates via SPI, which is natively supported by Arduino Uno, Mega, Nano, ESP32, ESP8266, Raspberry Pi, and most other popular microcontrollers. Simply connect the VCC, GND, CS, MOSI, MISO, and CLK pins to get started.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use this board with both PT100 and PT1000 RTD sensors?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. This converter board supports both PT100 (100Ω at 0°C) and PT1000 (1000Ω at 0°C) platinum RTD sensors. You may need to adjust a reference resistor or configuration jumper on the board depending on which sensor type you are using — refer to your module's datasheet for configuration details.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the operating voltage for this MAX31865 module?\u003c\/h4\u003e\n\u003cp\u003eA: The module supports both 3.3V and 5V supply voltages, making it compatible with a wide range of microcontrollers and single-board computers without the need for a level shifter in most common setups.\u003c\/p\u003e\n\u003ch4\u003eQ: What libraries can I use with this module for Arduino?\u003c\/h4\u003e\n\u003cp\u003eA: The most commonly used Arduino library for the MAX31865 is the Adafruit MAX31865 library, available through the Arduino Library Manager. It provides straightforward functions for reading temperature in Celsius and Fahrenheit from your PT100 or PT1000 sensor.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Is the MAX31865 RTD converter board compatible with Arduino Uno and Mega?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes!
