YINGHUA EZ31865 V1.0 Module PT1000 PT100 2/3/4 Wire Max31865 3D Printers Accessories

SKU CH-5KCJ-2Z24T

EZ31865 V1.0 module reads PT100 and PT1000 sensors in two, three or four-wire configurations using a MAX31865 chip and accepts 3.3 to 5 V power

  • Supports PT100 and PT1000 sensors for flexible temperature measurement
  • MAX31865 chip delivers high-performance signal conditioning
  • 2, 3, and 4-wire configurations suit various wiring needs
  • Operates from 3.3 V to 5 V for broad system compatibility
  • Single control board simplifies 3D printer integration

EZ31865 V1.0 temperature module

The EZ31865 V1.0 board integrates a MAX31865 chip to read PT100 and PT1000 resistance temperature detectors. It accepts two, three or four-wire sensor connections for flexible wiring. Power input ranges from 3.3 V to 5 V with a separate VCCIO supply. The module is intended for 3D printer temperature monitoring and control.

Makers adding precision temperature sensing

Builders upgrading a printer hot-end or heated bed with RTD sensors will find the multi-wire support useful. Users who only have thermistor inputs on their controller board cannot use this module directly. Projects requiring thermocouple or infrared sensing need a different interface. The board suits hobbyist and experimental setups rather than industrial process control.

MAX31865 chip with 2/3/4-wire RTD support

The defining specification is the MAX31865 converter paired with selectable two, three or four-wire measurement for both PT100 and PT1000 sensors. This combination determines wiring flexibility and achievable accuracy. No other single parameter governs compatibility as directly as the sensor interface mode.

Questions about this item

How can I confirm the EZ31865 V1.0 module is reading temperature correctly after wiring a PT100 sensor?

Connect a known PT100 sensor using 2, 3 or 4 wires, power the board with 3.3V to 5V, then compare the reported value against a reference thermometer at room temperature.

What comes in the package and what must I source separately for the EZ31865 V1.0 board?

The box contains one EZ31865 V1.0 control board; you must supply PT100 or PT1000 sensors and the connecting wires yourself.

Which sensor type should I select — PT100 or PT1000 — for the EZ31865 V1.0 module?

Both PT100 and PT1000 are supported; choose PT100 for wider industrial availability or PT1000 for higher resistance per degree, matching your printer firmware expectations.
