Yes, I bought the max31865 module from the distributor and the product has the same logo as your avatar on it.

@FestumZ this is the MAX31856 library repo. Can you please confirm which sensor and which library you are using?

FestumZ commented

@siddacious I use the MAX31865 module and the Adafruit_MAX31865.h library.

@FestumZ This is probably best handle in the forums:

Post photos of your setup there so we can make sure it's not hardware first.
