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

MAX31865 V2.0 is a dedicated high-precision temperature acquisition module designed for 3D printer hot end and heat bed temperature monitoring. Centered on the MAX31865 dedicated RTD conversion chip, it accurately converts tiny resistance changes of PT100 and PT1000 platinum thermal resistance sensors into readable digital temperature values, offering far higher measuring accuracy than ordinary thermistor modules, effectively avoiding printing defects caused by temperature deviation.

The module communicates with the main control board via SPI interface, featuring fast response speed and powerful electromagnetic interference resistance in the complex electrical environment of 3D printers. It is directly plug-and-play compatible with BIGTREETECH SKR V1.4 and SKR 2 series open-source motherboards, only requiring simple firmware parameter modification to complete deployment.

Built-in basic reverse connection and overvoltage protection circuits can effectively prevent module burnout caused by miswiring or voltage surge. Widely used in FDM 3D printer hot end temperature closed-loop control, industrial small equipment temperature testing and electronic temperature measurement DIY projects, greatly improving printing stability and finished product quality.
