The replacement was also DOA. See REVIEW for details.
UPDATE: I had written a previous review on this product and gave it a 1-Star rating. I was issued a return and replacement of the identical part. For 55 years I've done extensive work in engineering, much of it designing and having fabricated circuit boards for microelectronics. In some of my design and development projects, I often use modules such as this one from HILETGO to good success. The first one of these 31865 boards from them was DOA. I didn't spend much time investigating the board itself and returned it for a replacement. The replacement arrived today and it was a great disappointment that it too did not work. Fortunately, I had previously ordered and implemented the exact-same 31865 module but from a different seller. It works perfectly. Receiving TWO boards in quick succession, both DOA, I decided to look into why. As a result, including this review, I have spent the better part of 4 or 5 hours doing that. To begin with, precision PCB's at this scale have margins between component pads and circuit traces that is necessarily extremely small. To adequately examine the quality of the reflow soldering process and the component placement, it's necessary to put the part under high magnification. (I wish that I had a macro-lens to give you a real good look at what I found but suffice it to say that there were solder artifacts (little balls of solder too small to see with the naked eye but large enough to span the gaps between pins of the 31865 chip (as well as other places). These gaps are so small that don't even have tools which can remove those which shorted some pins. These shorts are measurable with a multimeter.The bottom line is that I've spent enough time on this seller's products. With a history of supporting them in the past and never been disappointed for more than a decade (as I recall), it's disheartening to write such a review. However, I know from experience that much time can be wasted questioning one's own SPI bus hookups, software, or even soldering joints. Since we expect that the modules will not be defective (certainly not two in a row), we waste a tremendous amount of time with this type of fault due to quality deficiencies. Perhaps this is just a bad batch of boards - a temporary glitch in the manufacturing - who knows. What I wanted to do here was convey MY experience with this batch of boards while pointing out that perhaps this is an outlier set of quality problems. I hope so but, in the meantime, I will just avoid this particular board from HILETGO. Good luck folks.

Ok, I struggled but got something, eventually.
I won't go into how long it took me to not get fault readings.I spent a week working on this, thinking I checked everything, and finally saw I had my SDI and SDO crossed.Afterwards, I was getting consistent readings. not accurate, but at least consistent.

Nice!
This was perfect for my RTD amplifier requirement. It came with all the pin headers and screw terminals required and is compatible with the existing microcontroller libraries.

Great RTD interface. Replica of Adafruit version.
Instructions would be nice, but this is basically the Adafruit MAX31865 RTD module. So instructions can be found on the Adafruit website. Otherwise, this module provides a convenient and streamlined interface for the PT100 / PT1000 RTD's. The output is very accurate and consistent. A 'nice to have' would be a redesigned module that can handle more than one RTD and revised code with the flexibility to initialize multiple classes for multiple RTD's.

Did not work
Unfortunately my sensor did not work at all with my PT100. I was able to confirm the PT100 as working properly, which was a 3 prong sensor. I cut the appropriate trace and tested with a multimeter to confirm the trace was cut. I applied solder on the appropriate solder joint for my 3 wire PT100.When connecting to my microcontroller with SPI protocol I only got readings of 0 degrees consistently. No shorts or errors. Upon further testing it seemed as if the main chip on the board was faulty. Very disappointed.

Great Unit but RTDs Only
This is for RTDs only, which is the reason I got it. It is a nice unit because it will accept a 4 wire RTD which will allow for the best accuracy you will get out of an RTD. Great unit and highly recommended!

This item is not a thermocouple sensor amplifier
I bought this unit needing a thermocouple sensor amplifier. This unit does not appear to be a thermocouple amplifier, but rather a PT100 RTD "amplifier." I still did not see details if this is for a RTD with an alpha of 0.00385 or 0.00392. Ignore the posting title and read the details carefully more carefully than I did.
