Product Details

The MAX31865PMB1 peripheral module (Pmod) provides the necessary hardware to interface the MAX31865 RTD-to-digital converter to any system that utilizes Pmod-compatible expansion ports configurable for SPI communication. The IC is an easy-to-use resistance-to-digital converter optimized for platinum resistance temperature detectors (RTDs). This module is set up to operate with a PT100 platinum RTD.
For full range accuracies, other RTD types, and detailed information regarding operation of the IC, refer to the MAX31865 IC data sheet.
