SMUGDESK MAX31865 V2.0 RTD Module PT100 PT1000 SPI

SKU CH-F6XV-PRCDW

High-precision RTD module converts PT100 or PT1000 sensor signals via SPI for accurate 3D printer temperature control

  • High-precision RTD conversion with MAX31865 V2.0 chip
  • Supports PT100 and PT1000 platinum resistance probes
  • SPI serial bus for fast noise-resistant data transfer
  • Direct pin-header fit for SKR V1.4 and SKR 2 boards
  • Reverse power and overvoltage protection for safe operation

RTD module for 3D printers

The SMUGDESK MAX31865 V2.0 converts PT100 and PT1000 platinum resistance sensors into digital temperature readings over SPI. It targets printer builders and industrial users who need higher accuracy than standard thermistor circuits can provide.

Compact PCB with protection features

The board layout includes reverse-connection protection and overvoltage safeguards to survive wiring mistakes during long print sessions. Standard SPI signalling gives stable data transfer across the printer frame without complex rewiring.

Direct fit for SKR control boards

Pin headers align with BIGTREETECH SKR V1.4 and SKR 2 motherboards, so configuration only requires a firmware parameter change. No extra cables, adapters or software packages are bundled with the module.

Questions about this item

What SPI interface does the MAX31865 V2.0 module use for data transmission?

It uses a standard SPI serial bus with MISO, MOSI, SCK and CS pins for stable, interference-resistant communication with the host controller.

What physical connections are needed to mount the module on a BIGTREETECH SKR V1.4 or SKR 2 board?

The module provides pin headers that align directly with the corresponding headers on SKR V1.4 and SKR 2 boards for plug-and-play installation.

How is the module configured in firmware after wiring it to the control board?

Only simple firmware parameter changes are required; no complex circuit modifications are needed once the hardware is connected.
