🌡️ Highly Efficient HiLetgo PT100 MAX31865 RTD Temperature Thermocouple Sensor Amplifier Module for Arduino Review

This is RTD only so I bought it. This is a good device as you can connect a 4 wire RTD to it giving you the best accuracy you can get from an RTD. Great unit! I advise!

Bought two, they worked exactly as advertised (and matched the much more expensive Adafruit model exactly). The resistance/temperature readings were very stable. I used it with a Particle Photon microcontroller. I want to buy more but they are sold out now!

The device was operational. I played around with this for about an hour to make sure it connected properly to my Arduino. Visually inspecting the components and solder joints, I noticed that the "FB1" ferrite bead on the side that connects to the MAX31865 was unsoldered. VDD performance. After soldering the connection, the board worked.

I bought this unit and I need a thermocouple sensor amplifier. This device does not look like a thermocouple amplifier but more like an RTD PT100 "amplifier". I still haven't seen the details of whether it's an RTD with an alpha of 0.00385 or 0.00392. Ignore the post title and read the details more carefully than I did.

Instructions would be nice but this is basically an Adafruit MAX31865 RTD module. Instructions can be found on the Adafruit website. Otherwise, this module provides a convenient and simplified interface for PT100/PT1000 RTDs. The output is very precise and consistent. It's "nice" to have a redesigned module that can handle more than one RTD, and revised code with flexibility to initialize multiple classes for multiple RTDs.
