MAX31865 V2.0 RTD Temperature Sensor Module, PT100 PT1000 to Digital Converter SPI Thermocouple Board Compatible with SKR V1.4, SKR 2 3D Printer Mainboards

MAX31865 V2.0 temperature sensing module is a professional RTD-to-digital converter board customized for FDM 3D printers. Built with the high-performance MAX31865 dedicated chip, it converts analog resistance signals from PT100 and PT1000 thermal resistors into precise digital temperature data via SPI communication.

This module features fully compatible signal protocol with mainstream BIGTREETECH control boards including SKR V1.4 and SKR 2. It solves the low precision and temperature drift issues of ordinary thermistor sensors, greatly improving temperature control accuracy for hotends during high-temperature printing of ABS, PETG and other special filaments.

The upgraded V2.0 circuit adds optimized filtering and isolation components to suppress electromagnetic interference generated by stepper motors and heating cartridges, avoiding abnormal temperature jumps or false overheating alarms during continuous printing. Clear solder terminals and standard pin definition simplify wiring work without complicated soldering adjustments.

It supports wide measuring temperature range and stable real-time data feedback to the mainboard, enabling more reliable thermal protection and constant-temperature printing. Small size saves installation space inside printer cases, ideal for DIY 3D printer builders, printer maintenance and industrial precision temperature monitoring projects.
