This PCB is designed for a MAX6675 and I am sure it will work fine with this chip. The unit selling at this offer is equipped with the better MAX31855 and was only able to work after some small modifications: According to the datasheet no connection is allowed between T- and GND as the MAX6675 needs this link. So I was not able to get this thing working until I cut the trace between pin 1 and 2. After that I got readings from my thermocouple but there were not correct. After adding a capacitor (47 or 100nF) between T+ an T- it works flawlessly.
